We&#x27;re looking for an equation for this function that is on the graph. Now, when I look at this, I know it&#x27;s gonna have some form like Why equals some constant or X or formal play by Simple says by X X y equals some constant. So my question becomes, What is that constant? Well, I noticed then when X was one. Why was all the way down here at negative eight? So that means X times Why must equal negative eight. So we have X y equals negative eight. If you want this as why equals form well, if you divide both sides by X, we get why equals negative eight over X. But there is your equation. X y equals negative eight or Y equals negative eight over X.

So we have an equation that looks like this. That is a graph that looks like this. Now, when I see this, I automatically think it&#x27;s gonna have some form similar to this. Only my question is what&#x27;s really my number right here. Well, to do that, I went to my points. Now I saw that when X was one. Why was too So that means I&#x27;m gonna change this one to a to and get why equals two over X. So we can write this as why equals two over X. We could also multiply both sides by X and get X Y equals two. So, depending on what form you&#x27;re looking for, this is the equation for a graph.

We&#x27;re trying to find an occasion for this function. Now, when I look at this, I automatically think it&#x27;s gonna be in some form like y equals one over X or X y equals some constant. Now notice that I got X Waigel some constant just by multiplying both sides by X. So we&#x27;re gonna have some number on the top. And I know it&#x27;s not gonna be one perfectly, but I&#x27;m looking for that number and then we can figure it out from our points. So when I look at this, I noticed that when X is one my why is six I also noticed that when X is too, Why is three? So that tells me something that tells me when I multiply my X and Y together, I&#x27;m gonna get it equal to six. So my equation is X y equals six. If you want to, you could divide both sides by X and get why equals six over X

So we have. We have been given that X is equivocal by and why his quota One very tree on. We need to find over. Listen between the videos exam away on We have been told that X and Y ready mostly so extent like and better. 10 has X who I must be quartered on stent where he is not a cord of zero. No, to get the random care, we replace the letters of X and y here. So by in do one by tree, this is K just Google by phone tree No replacing the world with this and the Christian Rikkert eggs. Why is a total fire phone tree? So this implies pits Tree X and C Where do by upon why? Oh, the X Why buy whichever way we can? Right? So there&#x27;s become self I know from the Grissom did nothing in the U. S. Radios and I&#x27;ll pick send way

So we have the point. Negative five. Negative three. I don&#x27;t need to write the equation for direct variation. So direct variation graph equation is why it was K X. So we have a wide value and x value, however missing this constant variation. Kay. So another case ratio. Why? Divided by X. So he played in our why value, which is negative. Three divided our X value, which is negative. Five. We get a positive three fits because a negative divided by rh negative is a positive. So they&#x27;re gonna take this value and plug it into our original equation. Okay, so now we&#x27;ll have why equals 3/5 x. So no need to plot this someone a draw. Ah, data table data chart. And we wanna plug in X values so that we can get some wine values so minimal. I&#x27;m gonna use X values and increments of five because we have a bottom in our denominator. And I don&#x27;t really like dealing with fractions, so I&#x27;m gonna try to get rid of those. So I like to do to negative numbers. Somebody negative. 10 negative by then. Zero in five into. So let&#x27;s take our equation. Take it. Six. So basically want supply through its times each of our X values. So the snake to 10 understood denominator would. So this cancels and it&#x27;s becomes too. So you can get negative six here or what? Secondly, Taking 3/5 times negative five thes council. We&#x27;re left with negative three anything times 00 And then these would just be the positive versions of those. So we have points and I want to have to change the graft belt here. So this would be too 468 10 246 es intent. So now we can plot these. So we have negative 10. Negative six. Do we have negative Five negatives. Three. Then we have 00 then fun 30 and then 10. Positive. Six. If you just connect the dots, we have a graph of our equation.

So in this question, we have been given that the red low picks his equal toe be five and the Bradley, Or why is equal to tria born by No, we need to find out a Christian representing you. Listen better next time, right? Says that a certain area and mostly very so worry nose radius. And we know that X Y is a quarter. Okay, Is the prison representing in those reasons as that is a concert of it is And it is not equal to zero? No, in order to find out the world. Okay, we can replace the where aerobics and why here. So what did you buy into a tree upon by? Is he Kordell Que? This implies K is equal to or be city 936 27. So case 27 year now replacing this value in the sea Christian There&#x27;s a primary Christian, so we can replace them. Endo gear here So we&#x27;ll get the finally Christianized X Do I as a gordo 27 or X is a gurgle 27 upon Why? So this is a fine now from all the christen her present danger. Listen, Britain Extend Way says that X ray A in the
