Note that slope formula is: (y₂ - y₁)/(x₂ - x₁) = slope
For the first one, set:
(x₁ , y₁) = (-3, 2)
(x₂ , y₂) = (3, -2)
Plug in and solve: (-2 - 2)/(3 - (-3) = -4/6
Simplify: -4/6 = -2/3
-2/3 is your answer

Do the same for the next question
(y₂ - y₁)/(x₂ - x₁) = slope
(x₁ , y₁) = (-8, -3)
(x₂ , y₂) = (-4, 0)
(0 - (-3))/(-4 - (-8))
Simplify. Note that two negatives = one positive
(0 - (-3))/(-4 - (-8)) = (0 + 3)/(-4 + 8) = 3/4
3/4 is your answer
