Question

Please help, I'll give you a medal!

Which pair of points has a negative slope?
A. (-3, 17) (2, -8)
B. (-3,13), (3,17)
C. (4,26) (-2,-10)
D. (4,14), (-2,-4)

Answer 1

\[slope =\frac{ y_{1} - y_{2} }{ x_{1} - x_{2} }\]

You will need to calculate the points given to find the slopes.

Answer 2

you can calculate them, but you dont need to really

Answer 3

if you order the pairs such that the x parts are low to high; check of the y parts get smaller

Answer 4

for example:

(4,14), (-2,-4): this one is out of order soo

(-2,-4) (4,14), thats better

now we can see that 14 is bigger than -4, so this has a positive slope

Answer 5

Okay, so can you check my answer?

Answer 6

which one do you pick?

Answer 7

I honestly don't get it and have no idea, I'll go with B.

Answer 8

(-3,13), (3,17); the x parts are in order

so the y parts go from 13 to 17 ... they get bigger, so this slope is positive

Answer 9

Let me try again!

Answer 10

A. Maybe...?

Answer 11

lets check it :)

(-3, 17) (2, -8) the x parts are in order:

y moves from 17 to -8; so this is in a downward direction which IS negative.

A has a negative slope. Now if you have to define the value of the slope, the formula given to begin with would work out swell.

Answer 12

SO it's A??

Answer 13

A works, yes.

Answer 14

Awesome, thank you so much!

Answer 15

good luck
