Write an equation in the form y equals mx plus b of the line that is described.
00:05
The line rises from left to right, it passes through the origin, and a second point with equal x and y coordinates.
00:12
So, first thing that we need to do is, if we are ever writing the equation of a line in slope -intercept form, we need to figure out what is my m, or your slope, and what is my y -intercept.
00:23
So, for this one, first of all, we're told that the line rises from left to right, which indicates that there is going to be a positive slope.
00:35
Okay? the other thing that we are told is that the line passes through the origin, which is the point 0 ,0, right smack dab in the center.
00:44
If we know the line is passing through there, we know that our b -value is 0, because our y -intercept is 0 ,0.
00:51
So, automatically, we already have our y -intercept.
00:54
The other piece of information that we're given is that the line passes through another x ,y coordinate point, where x and y are the same number...
