Question

Write the equation of a line in slope-intercept form that is perpendicular to the line

Answer 1

Gradient of line given = 3/5
(Gradient of line)(Gradient of perpendicular) = -1
(3/5)(Gradient of perpendicular) = -1
Gradient of perpendicular = -5/3

(y-y1) = m (x-x1),
where m is gradient of perpendicular
x1y1 is coordinate of a point the line passes.

(y-4) = -5/3 (x+9)
