Question

Fine the slope(rate of change) (7,9) (10,6)

Answer 1

for points (x₁,y₁) and (x₂,y₂)
slope=
`(y_2-y_1)/(x_2-x_1)`

(x,y)
(7,9)
(10,6)

x₁=7
y₁=9
x₂=10
y₂=6


slope=
`(y_2-y_1)/(x_2-x_1)`
slope=
`(6-9)/(10-7)`
slope=
`(-3)/(3)`
slope=-1

Answer 2

9-6=3
7-10=-3
the slope will be -1 because 3 over -3 is -1 which is like dividing 3 and -3
