B. -1/6
C. 6
D. -6

Answer 1

Answer 2

the product of the slopes of perpendicular lines is -1

first do you know the slope of y = 6x + 2 ?

Answer 3

no

Answer 4

the slope-intercept form of the line equation is

y = mx +b

where m is the slope

by comparing y = 6x + 2 to the general form
what is m here ?

Answer 5

6?

Answer 6

correct

now we need m' the slope of the second line

we have m x m' = -1
so what's m' ?

Answer 7

.... IDK

Answer 8

6 x m' = -1
divide both sides by 6
what do you get ?

Answer 9

-1/6

Answer 10

-1/6?

Answer 11

correct
