Question

determine the slope of a line (0, -15) and (-2,4)

Answer 1

how do we do this please explain.

Answer 2

slope = m = (y2-y1)/(x2-x1)
your points (0,-15)-->(x1,y1)
(-2,4)-->(x2,y2)

Answer 3

slope can also be defined as rise / run or the change in y over the change in x

Answer 4

using the above formula for slope, with those points for the x1, y1, x2, y2 you should come to the answer just fine

Answer 5

19/-2=-9.5=ans.
this can be used to check your answer

Answer 6

how did you get that?

Answer 7

are you serious? I just completely explained to you.. just think a little, read what I have wrote and you should be fine

Answer 8

yes but i don't get how we divide which numbers by which.

Answer 9

okay so if you are given a point. which one is x and which one is y (#,#)?

Answer 10

(x,y) right?

Answer 11

oh wait i think i get it.

Answer 12

you are given 2 x's and 2 y's

Answer 13

rise / run = slope;
rise = difference in y
run = difference in x

Answer 14

difference --> subtraction just make sure if you put y1 in front on top you put x1 in front on bottom

Answer 15

or vice versa it doesn't matter.

Answer 16

Oh thanks a lot bud! I really appreciate it!
