Use the slope formula.
Subtract the y-coordinates.
Subtract the x-coordinates in the same order.
Divide the difference in y by the difference in x.

slope = m = (y2 - y1)/(x2 - x1)

slope = (5 - 7)/(-2 - (-1)) = -2/(-1) = 2

slope = 2
(-2, 5) ve (-1, 7)
y₁ = 5
y₂ = 7
x₁ = -2
x₂ = -1

m = (y₂-y₁)/(x₂-x₁)
m = (7-5)(-1 (-2))
m = 2/(-1+2)
m = 2/1
m = 2
