Question

HELP!!!!

Answer 1

Perpendicular lines have opposite slopes..so you can rearrange the equations into the form of y = mx + b(where m = slope) to see which one's have opposite slope.

Answer 2

can you give me an example?

Answer 3

y = 3x + 2
^ Slope

A perpendicular lines to this will have the opposite slope. Here, the slope is 3.

Here is an example of a line perpendicular to that:

y = -1/3x + 2

The slope here is -1/3.

When we say 'opposite', we flip it around and multiply it by -1.

3 is the same thing as 3/1

Flipping it around will give us 1/3, and multiplying it by -1 will give us -1/3.

Answer 4

ok so let me.

Answer 5

well I think the answer could be B @iGreen.

Answer 6

You got it! :D

Answer 7

ok thanks. :)

Answer 8

I just have one last question about this.

Answer 9

Why is it B and not C?

Answer 10

Oh, my bad, it is C..I plugged in C and I thought it was option B..lol.

Answer 11

Well, it's C, because the slope for the first one is 2, and the slope for the second one is -1/2.

But for Option B, the slope of the first one is -1/6, and the slope of the 2nd one is 2.

Answer 12

ok that is really helpful.

Answer 13

No problem.
