undefined

0

–2

Answer 1

m=y2-y1/x2-x1

Answer 2

\[\frac{ y-difference }{ x-difference }\]

Answer 3

Use the formula

Answer 4

Show me the working

Answer 5

And I will tell u wheter ur right or wrong

Answer 6

Hint: use y = mx + b for each point to get:

-7 = 3m + b
1 = -m + b

Isolate b in each equation to get:
b = -3m - 7
b = 1 + m

Set b = b to get:
-3m - 7 = 1 + m

Add 3m to both sides, then subtract 1 from both sides to to get:
4m = -8

Divide both sides by 4 to get

m = -8/4
m = -2

Since m represents the slope of a line, the slope, m, is -2

Answer 7

its m=-2 got it thanks
