So in this problem, i'm finding the distance between the two lines, y equals 15 and y equals negative 4.
00:08
Now, in order to do this on this graph, i'm going to have to scale my graph.
00:12
So i might scale it by, let's see, 2, 4, 6, 8, 10, 12, 14.
00:18
I would need to get up here for 15.
00:21
Let's scale it by 3.
00:23
So 3, 6, 9, 12, 15.
00:28
Okay, so that will work.
00:28
So for my y equals 15 and y equals negative 4, i could think of both of these in two ways if i think of them in slope intercept form.
00:38
Because i don't have an x term that's gone.
00:41
What that would tell me is that my slope must have been zero.
00:46
And then this second number is just my y intercept.
00:50
And i also know that a line with a slope of zero is horizontal.
00:55
Or i could graph it by creating two ordered pairs and connecting those two ordered pairs...
