I want to graph the line 4x minus y equals 8, and i'm going to do that using my x and y intercepts.
00:06
So to use my x intercept, i'm going to plug 0 in for y, because that is the y value for my x intercept.
00:15
So i've got 4x minus y, which is 0, equals 8.
00:20
4x minus 0 is 4x.
00:23
Divide both sides by 4 so we can get x by itself, leaving me with x equals 2.
00:28
That means my x intercept is going to be the order pair 2 comma 0, and i'm crossing that axis at x equals 2.
00:38
My y intercept, i'm going to use a similar procedure, and i'm going to plug in 0 for x this time, because that's my x value for my y intercept.
00:49
So i've got 4 times 0 minus y equals 8.
00:55
4 times 0 is 0, so negative y equals 8, together...
