Question

What is the slope of this line ((2,3) (5,5) (8,7)

Answer 1

`\huge\boxed{\text{the slope}=(2)/(3)}`

Explanation:

The formula of a slope

`m=(y_2-y_1)/(x_2-x_1)`

Put the coorcinates of the points:

(2, 3); (5, 5)

`m=(5-3)/(5-2)=(2)/(3)`

(2, 3); (8, 7)

`m=(7-3)/(8-2)=(4)/(6)=(4:2)/(6:2)=(2)/(3)`

The point (2, 3), (5, 5) and (8, 7) are collinear because have the same slope.
