Question

What is the slope between the two points (6, 20) and (2, 4)?

Answer 1

slope is "change in y" divided by "change in x"

Answer 2

slope = (y2 - y1) / (x2 - x1) when your points are (x1, y1) and (x2, y2)

Answer 3

y2 is 6 and y1 is 20

Answer 4

No, choose one point as "point 1" such as point 1 is (6,20), so x1 = 6 and y1 = 20

Answer 5

Use y = mx + b to solve. Input both points into the formula one at a time to get:

20 = 6m + b
4 = 2m + b

Answer 6

Or, you can do it that way.

Answer 7

Next, isolate b in each:

b = 20 - 6m
b = 4 - 2m

Answer 8

think so

Answer 9

Next set b = b

20 - 6m = 4 - 2m

Answer 10

The possible answers are
A. -4
B 4
C 1/4
D 1/4-

Answer 11

20 - 4 = 6m - 2m
16 = 4m
16/4 = m
m = 4

Answer 12

Sorry for the mistake

Answer 13

Thanks that's ok.
