to find slope, we can use the formula
m = (y₂-y₁) / (x₂-x₁)
we are already given two sets of points, so now we can plug it into our equation
x₁ = -4
y₁ = 2
x₂ = 5
y₂ = 8
m = (8-2) / (5-(-4))
m = 6 / 9
m = 2/3
the slope of the line through the points given is 2/3
the slope of the line through the given points of (-4,2) and (5,8) is 2/3
