Question

What is the equation in slope-intercept form of a line that is perpendicular to y=1/4x−1 and passes through the point (4, 1)?

Enter your answer by filling in the boxes.
y=___x+___

Answer 1

y=4x-15

This line passes through (4,1) and is perpendicular to y=1/4x-1

Answer 2

y = -4x + 17

Explanation:

Slope of the perpendicular line: -4

(4,1)

y-intercept: 1 - (-4)(4)

= 1+16 = 17
