Answer:
-1/2
Step-by-step explanation:
let's look at the change from the red point to the blue point
thus, (x₁, y₁) = red point = (-4, 1) and (x₂, y₂) = blue point = (-2, 0)
note that (x₁, y₁) and (x₂, y₂) can be interchanged
slope = change in y / change in x = (y₂-y₁)/(x₂-x₁) = (0-1) / (-2-(-4)) = -1/2 as our slope
