Answer:

Explanation:

M is the slope.

To begin, finding the slope would be the formula

(y2 - y1)

______

(x2 - x1)

y2 would be 7, while y1 would be 9

x2 would be -12, while x1 is -10

The equation is now

7 - 9

____

-12 - (-10)

7 minus 9 is -2, and -12 - (-10) is -2.

-2

__

-2

The answer of the slope would be 1, since -2 divided by -2 is 1.

For extra help, I can also find the y intercept.

y = mx + b is the formula. This is the slope intercept formula.

input either 7, or 9 into the y. I will be doing 9.

Input the x from the same coordinates, (which is -10).

9 = 1 (-10) = b

1 x -10 is -10.

9 = -10 + b.

To even this out, you must add 10 to each side, making sure -10 turns into a zero.

19 = b.

The y intercept is B.

I hope this can help.
