So for this problem, we're first asked to solve the equation for y so that it's written in slope intercept form.
00:07
So that's what we're going to do first.
00:10
And in order to solve for y, i need to isolate y.
00:13
So that means i will be using inverish properties to move this to x.
00:18
So in order to move to x, since it's positive right now, i will be subtracting 2x.
00:23
And whatever i do to one side of the equation, i must do to the other side.
00:27
So then i need to subtract 2x from the right side also.
00:30
By subtracting terms, i have left y equals 0 minus 2x.
00:39
And just so that we are being consistent, i'm going to rearrange my terms on the right side, so it matches slope -intercept form.
00:48
Okay.
00:49
So when we rewrite our equation, it's y equals negative 2x plus 0.
00:58
Or you could just write it as y equals negative 2x, since adding 0 doesn't change the value.
01:05
But i'm going to keep the plus zero at the end of the equation so that it's easier for me to graph later on.
01:13
Okay.
01:15
The second part of the problem asks me to identify the slope and the y intercept for this equation.
01:25
So if you look on the right side of the screen in the green handwriting, we have y ecosemex plus b, which is our slope intercept form...
