Question

Find the slope.
(-2,7) and (-1,2)

Answer 1

hey so do you know the slope formula?

Answer 2

no

Answer 3

ok, well, to find the slope between two coordinates, you use this formula for two coordinates (x1,y1) and (x2, y2):
1. slope = (y2 - y1)/(x2 - x1)

Answer 4

so in the case of your problem:
x1 = -2, x2 = -1, y1 = 7, and y2 = 2

Answer 5

so stick those into the slope formula and you will have your answer

Answer 6

you want to try it?

Answer 7

It would be (-2-7) (-1-2) right?

Answer 8

(5), (1)???

Answer 9

well, the slope is one number, that basically represents "for every x coordinate I move to the right, how many y coordinates do I move up?"

Answer 10

so the slope = (y2 - y1)/(x2 - x1) = (2 - 7)/ (-1 - (-2))

Answer 11

oops sorry messed up

Answer 12

or sorry did not mess up, the answer is -5/1 = -5

Answer 13

through (2,1) slope =-3/2

How do I write the slope intercept form of the equation?
