Question

Select the equations that are parallel and perpendicular to y = 1/4x + 7 and that pass through the point (-8,9)

parallel: y = 1/4x - 11
perpendicular: y = -4x + 23

Parallel: y = -4x + 11
Perpendicular: y = 1/4x - 4

Parallel: y = 4x - 7
perpendicular: y = -1/4x - 7

parallel: y = 1/4x + 11
perpendicular: y = -4x - 23

Answer 2

What is the slope of the line y = 1/4x + 7

Answer 3

how do i find it?

Answer 4

the last one is the correct answer

Answer 5

@jim_thompson5910

Answer 6

the slope of y = mx+b is m

Answer 7

in the case of y = 1/4x + 7, what is m

Answer 8

1/4

Answer 9

so that's the slope of any line parallel to that one

Answer 10

so that allows you to rule out choices B and C

Answer 11

is it D? @jim_thompson5910

Answer 12

it is, nice job
