Question

Find the slope between these two points:
(9,3),(19,-17)

Answer 1

Slope = -2

Explanation:

(9, 3), (19, -17)

(x₁, y₁) (x₂, y₂)

y₂ - y₁ -17 - 3 -20

m = ------------ = ------------ = -------- = -2

x₂ - x₁ 19 - 9 10

y - y₁ = m(x - x₁)

y - 3 = -2(x - 9)

y - 3 = -2x + 18

+3 +3

-----------------------

y = -2x + 21

I hope this helps!

Answer 2

it should be (-1) or (-10/10)
