What is the slope of (3,5) and (-3,-5)

slope m= -

Step-by-step explanation:

Slope is equal to the change in  y  over the change in  x , or rise over run.

The change in x is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise).

Substitute in the values of  x  and  y  into the equation to find the slope.

m = − 3 − (3 )    5 − ( − 5 )

Simplify.

m=-

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
