Please help find slope

Select two points

7/-2 and 5/-1

subtract y1 from y2 to figure out y's change

7 - 5 = 2 change in y

now we subtract x1 from x2 to figure out x's change

-2 - ( -1 ) = -1 change in x

The slope will just be the results of the change in y and x but in the order of rise/run

2/-1 = -2 is the slope

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
