We will begin with a coordinate grid.
00:05
If you have graph paper, i suggest using that.
00:10
And we will graph the line, y equals, for the slope, we'll use 3x plus 2.
00:21
So we know that the y intercept is a positive 2, and it has a slope 3.
00:28
So every positive 3 change in the y, we have a positive 1 change in the x.
00:37
Or we could think of it for every negative 3 change in the y, we have a negative 1 change in the x.
00:47
So our line's going to look like this.
00:52
We will do the same line but with a slope of negative 3, x plus 2.
00:59
So again the y intercept is still two.
01:02
This time for every negative three change in the y, we would have a positive one change in the x, or for every positive three change in the y, we have a negative one change in the x...
