Question

Would the slope of a line with two points at
(-2, -2), (-2, -4)
be -2? or -1/2

Answer 1

I think -2

Answer 2

(y2 - y1) / (x2 - x1)
(-2,-2)...x1 = -2 and y1 = -2
(-2,-4)...x2 = -2 and y2 = -4
now you sub
(-4 - (-2) / (-2 - (-2)
(-4 + 2) / (-2 + 2)
-2/0........you are going to have an undefined slope

Answer 3

That's what I thought but it doesn't give me that option.
It gives me 1/2, -1/2, 2, and -2.
Maybe i'm getting the points wrong?

Answer 4

(-2,-4) is definitely not on your line

Answer 5

I think so...because when you have 2 x terms that are the same....it is a vertical line with an undefined slope

Answer 6

Oh I read them backwards huh?

Answer 7

(-2,-2)..x1 = -2 and y1 = -2
(0,-3)...x2 = 0 and y2 = -3
now we sub
(-3 - (-2) / (0 - (-2)
(-3 + 2) / (0 + 2)
-1/2......this is your slope

Answer 8

THANK you. I appreciate the help a bunch.

Answer 9

yeah I think you got (2,-4) confused with (-2,-4) for some reason

Answer 10

(-,-) points are in the third quadrant
(+,-) points are in the fourth quadrant

Answer 11

(2,-4) would be on your line also

Answer 12

Oh dang. Whops yeah I did. I haven't had to graph anything in a while :I
