Question

What is the y-intercept of the line perpendicular to the line y = 3/4x + 3 that includes the point (3,1)

Answer 1

Explanation:

Slope of given line m= 3/4

perpendicular slope is - 1/ m = - 4/3

y = -4/3x + b sub in the given point to calculate 'b'

1 = -4/3 (3) + b

5 = b b = y axis intercept = 5

the new line equation becomes y = -4/3 x + 5
