Question

The lines shown below are perpendicular

Answer 1

Slope of green line:

`m = ( - 3 - 3)/(4 - ( - 4))) = - (6)/(8) = - (3)/(4)`

Slope of red line:

`m = (3 - ( - 5))/(3 - ( - 3)) = (8)/(6) = (4)/(3)`

The slopes of these two lines are negative reciprocals of each other.

Therefore, the correct answer is True (A).
