Answer:
The lines are not perpendicular
Step-by-step explanation:
in order to know if two lines are perpendicular, you can use the following equation:
m1 * m2 = -1
So you need to calculate the slopes of both lines, and if the product of the slopes is equal to -1 then the lines are perpendicular.
Slope of the first line
m1 = (y2 - y1) / (x2 - x1)
m1 = (-12 - (-10)) / (-5 - (-8))
m1 = (-12 + 10 ) / (-5 + 8)
m1 = -2 / 3
Slope of the second line
m2 = (y2 - y1) / (x2 - x1)
m2 = (-5 - (-6)) / (17 - 9)
m2 = (-5 + 6 ) / 8
m2 = 1 / 8
-2 / 3 * 1 / 8 = -1 / 12
This means the lines are not perpendicular.
