In the problem, we're being asked to solve the given equation by graphic.
00:04
So, if you have a graph and calculator, you're going to go to your y equals menu, and in y sub 1, we're going to type in the left -hand side of the equation.
00:11
But be careful, especially for the first fraction, that denominator needs to be in parentheses.
00:16
So we're going to have 1 divided by, and in parentheses, 0 .75x, closed parentheses.
00:22
And your second fraction is okay as this.
00:24
So minus 0 .45 divided by x.
00:28
Okay, and then you're going to scroll down to the y sub 2 equation, and you're going to enter in the right hand side, 1 divided by 9.
00:34
Now you can graph it, and if you're in that standard 10x10 zoom, you can see that first equation in red, but it's very hard to see this line for y sub 2 is 1 9th.
00:45
That's a horizontal line, and 1 over 9 is a very small decimal.
00:49
So what we're going to do is we're going to change our y values for our zoom.
00:53
So if you go to your window button, for your ymin, let's make it zero because one -ninth is positive, and let's make the y -max 1, because 1 -9th is less than 1.
01:03
So if we do that, now let's go ahead and press graph again...
