Question

What is the slope between the following points: (8,-1) and (-7,4)

Answer 1

The answer is D. -3
you subtract x2 for x1 over y2 for y1 then you'll get 15/-3 then simplify the fraction

Answer 2

The answer is: $\frac{-1}{3}$ or -0.3333333333333

BECAUSE:
X1 is 8
Y1 is -1
X2 is -7
Y2 is 4

WHATS IS FORMULA FOR SLOPE?
$\frac{Y2 - Y1}{X2 - X1}$

FURTHER EXPLANATION:
(X1, Y1) & (X2, Y2). Now, plug the coordinates in the formula.

$\frac{(4 - -7)}{(-7 - 4)}$
