Aiyana, let's draw both lines to solve the problem, as follows:
Let's confirm that the lines are neither parallel nor perpendicular:
Slope = (0 - 0)/(7 - - 2)
Slope = 0/9
Slope = infinite
Slope = (6 - 3)/(-5 - - 5)
Slope = 3/0
Slope = 0
Now, let's change the location of the lines, but using the same coordiinates:
In this case, the lines are perpendicular.
