In the diagram, we give the coordinates as follows
(0,-6) where 0 is x(1) and -6 is y(1)
Also,(3,3) where 3 is x(2) and 3 is y(2)
The slope of a line (m) can be solved with the formula below:
We then insert the coordinates into the formula
Therefore the slope of the line is 3.
Note: m and the slope are the same.
