Question

Consider the line -4x+5y=2.

Find the equation of the line that is perpendicular to this line and passes through the point (-7,-3).
Find the equation of the line that is parallel to this line and passes through the point (-7,-3).

Answer 1

Perpendicular and passes through (-7,-3) ---> y = 4/5x + 2.6

Parallel and passes through (-7,-3) ---> y = -5/4x - 11.75
