Question

Use slope to determine if lines AB and CD are parallel, perpendicular, or neither 9. A(O.-2), B(0,7), C(3.-5), D(6-5)mn (AB) .(CD) Types of lines

Answer 1

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.
