What is the equation in slope Intercept form of the line that passes through the point (2,-2) and is perpendicular to the line represented by y=2/5x+2

Answer 1

The product of slopes of perpendicular lines is -1, so

m = -1/(2/5) = -5/2

y = (-5/2)x + b

-2 = (-5/2)(2) + b

-2 = -5 + b

b = 3

y = (-5/2)x + 3
