What is the slope of the line that passes through the points -2, 15 and -8, -5

To find the slope you need to use the equation . (2, 15) and (-8, -5) is (x1, y1) and (x2, y2). , so the slope of the line that passes through the points -2, 15 and -8, -5 is two.

the answer is 15% decrease

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
