Question

What is the slope of (2,-5) and (-3,-10)

Answer 1

(y - yo) = m.(x - xo)

(-10 -(-5)) = m.(-3 - 2)

(-10 + 5) = m.(-5)

(-5) = m.(-5)

m = -5/-5

m = 1 <- Slope

(y - yo) = 1.(x - xo)

(y - (-10)) = 1.(x - (-5))

y + 10 = 1.(x + 5)

y + 10 = x + 5

y = x + 5 - 10

y = x - 5 <- Line

Answer 2

slope = 1

Explanation:

slope = (y-y') / (x-x')

S = (-10 - (-5)) / (-3 -2) = -5 / -5 = 1
