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.
