Question

The slope of any line perpendicular to AB, where A(0, -3) and B(4, 9) are two points on the line, is m = ___-3? < Is this correct?

Answer 1

the answer isn't -3

Answer 2

Would it be -1,3

Answer 3

it's not an ordered pair, but you're getting closer

Answer 4

So it's just 3 then?

Answer 5

no that's the slope of AB

Answer 6

Hmm =/

Answer 7

if some line has a slope of p/q, then the slope of any perpendicular line is -q/p

Answer 8

-1/3?

Answer 9

yep, it's -1/3
