Question

What is the slope of a line perpendicular to the line with equation y = 6x + 2?

Answer 1

A.6

B.-6

C.3

D.- 1/6

Answer 2

If you know the slope of the first line, then what do you automatically know about the slope of a line perpendicular to it? Use that property to compute the slope of the second line.

Answer 3

-6x + y = 4

you can move the variables around to get the form: y = mx + b, which is the slope intercept form.

y = 6x + 4

here: m = 6, b = 4

m is the slope of the line, so slope is 6

any line parallel to this line will also have the slope of 6

any line perpendicular to the given line will have the slope of: -1/m1

we know m1 = 6, so the perpendicular line will have the slope of: -1/6

Answer 5

There you go

Answer 6

So B is your ansswer

Answer 7

the answer is not B

Answer 8

if you have a line

y = mx + b

the slope of the line is m

the perpendicular line has a slope

\[m_{perpedicular} = \frac{-1}{m}\]

the product of the 2 slopes

\[m \times m_{perpendicular} = -1\]

so find the slope of your line.. and then find the negative reciprocal
