Question

Write an equation in point-slope form that is perpendicular to the line y=1/4x-9 and passes through (1, 1)

Answer 1

y - 1 = -4(x - 1)

Explanation:

Given line: y = 1/4 x - 9

Slope of given line: 1/4

Slope of perpendicular: -4

Point on line: (1, 1)

Equation of perpendicular line:

y - 1 = -4(x - 1)
