how would I find the slope for

(-2,-2) and (6,3)

(-3.1,5.2) and (-4.4, 5.2)

The slope m of the line through the

points (x1, y1) and (x 2, y 2) is given by

Slope Formula

m = y1 – y2

———-

x2 – x1

provided that x1 does not equal x2

so 3 – (-2) = 5 – because the minus changes the negative to a positive.

6 – (-2) = 8 – same thing as the first

so m = 5/8 (m is slope, thats how it is written in math)

for the second

5.2-5.2=0

and -4.4 – (-3.1) = -1.3

so that 0/-1.3 which is just 0 yup thats it

(y2-y1)/(x2-x1) so (3-2)/(6–2)=1/8 so 1/8 is the slope.The formula is the same for the second one. (5.2-5.2)/(-4.4–3.1)=(0/-1.3) that is the slopw of the second line. therefore the slop is zero

an ordered point is (x1, y1) (y1, y2) doesn’t matter which one’s which. Then you use the formula y2-y1/ x2-x1 or y1-y2/x1-x1. So for the first one it would be -2-3/-2-6 =-5/-8 = 5/8 as your slope.

use the equation to find slope.

y2-y1/x2-x1

for example, your first two points:

3+2/6+2

5/7

slope=5/7

so just use that formula and you can find the slope for your second points.
