We're given a pair of points.
00:04
We're asked to plot these points and find the slope of the line passing through them.
00:08
The points are negative 2, 1, and negative 4 or 5.
00:18
To plot these points, we'll draw the cartesian plane.
00:22
We see at the x values range from negative 2 to negative 4, so i'll draw the x -axis to range from 0 down to negative 5.
00:31
And the y values range from 1 to positive 5, so i'll draw the y -axis to range from 0 to positive.
00:39
5.
01:02
Therefore, our first point, negative 2, 1 is located about here.
01:07
Our second point, negative 4 or 5, is located about here.
01:14
Now to find the slope of the line through these two points, we'll use the slope formula.
01:22
This is the change in y values over the change in x values.
01:26
This is negative 5 minus 1 over negative 4 minus negative 2.
01:33
So this is equal to negative 6 over negative 2 or 3.
01:57
I'm sorry, i think i made a mistake here.
02:04
This y coordinate should actually be negative 4, negative 5...
