Question

What is the slope of a line perpendicular to the line whose equation is y = − 2/7 x − 5?
A. -2/7
B. -7/2
C. 2/7
D. 7/2
i got A is that correct?

Answer 1

No, if you have a line perpendicular, you must take the opposite reciprocal of the given slope.
The opposite reciprocal, in this case, would be 7/2, so D.

Answer 2

correct answer ^

Answer 3

a is right because its the slope of the line i'm in algebra 2 i bet she doesn't know what she is doing the correct answer is a because it asked for the slope the line.

Answer 4

But you just gave the slope of a line parallel to it, not perpendicular.
I learned that with a perpendicular line that you must take the opposite reciprocal of the given slope o.e @elwellcassie1998

Answer 5

no i didn't i know what i'm doing i'm not stupid

Answer 6

I never said you were o-o @elwellcassie1998

Answer 7

@vangoo97 is correct to find the slope of line perpendicular to another line you take the negative reciprocal of the original slope.

Answer 8

i didnt say u ever did im just saying that i know what im doing i passed that class with a A-

Answer 9

So do I, I finished with a 98...not bragging, just stating facts.
I quite enjoy math. @elwellcassie1998
I didn't mean to start anything o.e

Answer 10

its fine lol and wow a 98 lol

Answer 11

97 damn you win

Answer 12

Yeah, I'm a nerd, and I do math in my free time tbh xD
Math has always been my thing (and singing/music)
So, if you ever need math help, I will try to help lol cx

Answer 13

yeah what math class are you in right now

Answer 14

Analytic Geometry, hbu?
