What is slope of the line that passes through (3,2) and (-1,-8)

5/2

Step-by-step explanation: Start with the slope formula.

The slope formula can be read as “slope equals the second y-coordinate minus the first y-coordinate over the second x-coordinate minus the first  x-coordinate.”

So we have -8 - 2 over -1 - 3 which is -10/-4.

Make sure to write your slope in lowest-terms!

-10/-4 can also be written as 5/2.

(x+3)(x+7)

step-by-step explanation:

a)(x-2)^2+(y-1)^2=9
