What is perpendicular and parallel equation to this

Question

Y=-7/2x+7

what is perpendicular and parallel

Answer 1

y=(-7/2)x+7

parallel is

y =(-7/2)+ b where b = any real number but not = 7

parallel lines have the same slope, but different y intercept

perpendicular is

y =(2/7)x + b, where b = any constant, any real number

perpendicular lines have negative inverse slopes
