Question

Calculate the slope that passes through the points (7, -4) and (4,8)
I got 4/-3 but that's not one of the answers...

Answer 1

how did you get -4/3?
show the steps.

Answer 2

let me see. you did 8-(-4) = 4 for the numerator, correct?

Answer 3

I did the y2 - y1 / x2 - x1
8-4/4-7
4/-3
/= fraction bar

Answer 4

that's how I did it, but it's not the answer :/

Answer 5

what is -(-2)?

Answer 6

there isn't a -2 in the equation...

Answer 7

well? what is the negative of a negative number?

Answer 8

I know. answer my question though.

Answer 9

a positive?

Answer 10

yes. so then 8-(-4) = ?

Answer 11

I re-did the problem and got 4

Answer 12

that is wrong.

Answer 13

positive 4

Answer 14

you did
8-(-4)/4-7 = 12/-3
what is 12 divided by -3? +4 or -4?

Answer 15

positive 4

Answer 16

no. a positive number divided by a negative number gives a negative number.
the answer is -4
