Slope intercept form equation for the line that is perpendicular

Question

What is Y=2/5x-3 (2,-3) in slope intercept form

Answer 1

The product of slopes of perpendicular lines is -1, so the slope of the perpendicular line is

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

y = (-5/2)x + b

Find b from the given point.

-3 = (-5/2)(2) + b

Solve for b and finish from here.
