Question

Identify an equation in point slope form for the line perpendicular to y = -1/3 x - 6 that passes through (-1,5)

Answer 1

y + 1 = 3(x - 5) Answer

Explanation:

Find the slope of the perpendicular line.

m1 * m2 = - 1

m1 = - 1/3

m2 is the slope of the perpendicular

(-1/3) * m2 = - 1 Multiply both sides by -3

-(3)(-1/3) * m2 = -1 * -3

m2 = 3

The slope of the perpendicular line is 3

Find the equation of the line.

m = (y - y1)/(x -x1)

y - y1 = m(x - x1) is the equation of the line.

y1 =5

x1 = - 1

(y - - 1) = 3(x - 5)

y + 1 = 3(x - 5) Answer
