Write an equation for a line perpendicular to y = 5 x − 5 and passing through the point (-15,8)

Answer 1

m=-1/5 = the perpendicular line's slope = the negative inverse of 5. Change the sign and flip the number upside down

y-8 = (-1/5)(x+15) = -x/5 - 3

y = -x/5 +5 is the equation of a perpendicular line through the given point (-15, 8)
