We need to solve the following system by graphing.
00:04
So the first one we're going to rearrange, and this becomes x minus 1 is equal to y.
00:09
Our slope is the number in front of x, which is 1.
00:11
Our b, which is our y intercept, is negative 1.
00:14
So we start at negative 1, and we'll go up 1 over 1.
00:23
Our second one, we move the y over, so it becomes negative, move the x over, so that becomes negative 2x plus 8.
00:29
Our slope is the number in front of x, and our b, which is our y intercept is 8.
00:33
So 1, 2, 3, 4, 5, 6, 7, 8.
00:37
And negative 2 means we go down 1 over 1, down 2 over 1...
