Question

Which equation represents a line which is perpendicular to the line y = 1/6x - 1 O 6x + y = 1 O 6y – x = 42 O x + 6y = -36 O 6x - y = 8

Answer 1

a) y= -6x+1

1) Perpendicular Lines have a reciprocal and opposite slope considering the original function: -1/m

So the slope of that perpendicular line is m = -6

2) Examining the options, let's rewrite them into the slope-intercept form

a) y=-6x +1

b)y=1/6x +42

c) y=-x/6-6

d) -y=-1/6x+4/3

3) So the answer is a) y= -6x+1
