We're given a set of equations and asked to solve it by graphing.
00:08
And so what i'm going to do is i'm going to try to graph these, and they're in y -equals mx plus b form.
00:16
So if i just draw a set of axes, put a scale on the axes, which i'm going to do, and then i'm going to try to graph the two lines.
00:31
Okay, these are my axes.
00:34
So then i'm going to label them.
00:37
And i'll just go up, one, two, three, four, five, six, let's say.
00:41
And the same thing up here, one, two, three, four, five, six.
00:46
And then back, one, two, three, four, five, six.
00:49
So that's minus six.
00:51
And then there's minus six there.
00:55
So i'm going to color this one in blue.
01:00
And i'm going to start, this is the y intercept.
01:02
So i'm going to start at minus two.
01:04
And then the slope, which is in front of the x is one.
01:07
So when i go over one, i go up one.
01:08
So there's my slope...
