So my objective on this problem is to write the equation in slope intercept form, which is going to be y equals x plus b, with the given information.
00:08
And that information is that the line has a slope of negative 9, and it also passes through the point to negative 4.
00:14
It's important to know that when you have a slope intercept equation completed, that the slope will have gotten replaced with the number, and the y intercept will have gotten replaced with the number.
00:23
So as of right now, the only box that i could fill would be my slope with negative 9.
00:28
I don't know my y intercept.
00:30
So i'm going to label my information.
00:33
So slope i would label with m, and then my ordered pair i would label with x and y, since that's how we always label ordered pairs.
00:40
Next, i would substitute all of this information into my y equals an x plus b equation.
00:45
So y will get substituted with negative 4, m will get substituted with negative 9, and x will get substituted with 2.
00:52
B cannot get replaced, since i don't know what it is...
