The equation of the perpendicular line if it passes through the second point each time.

a. (-2, 2) (4, -4)

b. (-5, -3) (6, -3)

c. (6, 1) (-6, 4)?

Question is poorly worded.

I will do the first one based on my interpretation

slope of line between points (-2, 2) and (4, -4)
= (-4-2)/(4-(-2))
= -6/6 = -1
So the slope of a perpendicular line would be +1
and it passes through (4,-4), so

y + 4 = 1(x-4)
