Question

What is the slope of the line that passes through the points (2, 1) and (8, 9)

Answer 1

`m=(4)/(3)`

Explanation:

Slope can be calculated using following formula

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

Here

`(x_1, y_1) = (2, 1) \ \ \ and \ \ \ (x_2, y_2) = (8, 9)`

Substituting values in formula

`m=(9-1)/(8-2)\\m=(8)/(6)\\m=(4)/(3)`
