Question

which points have a slope of 1/3?
(3, 2) (9, 4)
(2, 3) (9, 4)
(2, 3) (4, 9)
(3, 2) (4, 9)

Answer 1

Hint: use the slope formula

m = (y2-y1)/(x2-x1)

Answer 2

do you know it though?

Answer 3

so for instance, choice D has a slope of...


m = (y2-y1)/(x2-x1)


m = (9-2)/(4-3)


m = 7/1


m = 7

Answer 4

So choice D does NOT have a slope of 1/3

Answer 5

okay then.
