Question

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

Answer 1

Answer:

$m=\frac{4}{3}$

Step-by-step explanation:

Slope can be calculated using following formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Here

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

Substituting values in formula

$m=\frac{9-1}{8-2}\\m=\frac{8}{6}\\m=\frac{4}{3}$
