This problem says, write the equation in slope intercept form.
00:05
Now we know that slope intercept form is y equals mx plus b.
00:12
M is our slope and b is our y intercept.
00:17
So the first thing we want to do is look at problem a.
00:21
We're going to find our slope.
00:24
So our slope is going to be rise overrun.
00:27
So that's vertical change.
00:30
We're increasing.
00:32
By 2 over horizontal change 1, 2, 3, 4 increasing by 4.
00:39
So our m, our slope is 2 over 4, which equals 1 1 1⁄2.
00:49
Our b is our y intercept and that is located here.
00:53
So our b is 4.
00:57
That's where we intersect the y axis.
01:01
So this equation would be y equals 1 half x plus 4.
01:10
Looking at problem b, we're going to first find our slope...
