Two points (-4,-7) and (8,-13) in slope-intercept form

Step-by-step explanation:

(-4,-7) and (8,-13)

y2 = -13, y1 = -7, x2 = 8, x1 = -4

Slope m = (y2 - y1)/(x2 - x1)

m = (-13 + 7)/(8 + 4)

m = -6/12

m = -1/2

And the equation is

y - y1 = m(x - x1)

y + 7 = -1/2(x + 4)

y + 7 = -x/2 - 2

y = -x/2 - 2 - 9

y = -x/2 - 11

the answer is 62.8 cubic units

probably .5

i can on others if necessary.
