Question

How do you find the slope of the line that passes through (3,5) and (8,15)?

Answer 1

`color(brown)(Slope = m = (15 - 5) / (8 - 3) = 2`

Explanation:

`"To find the slope of the line passing thru " (3,5), (8,15)`

`color(crimson)(Slope = " (rise) /( run) = "("change in y's ) / (change in x's )"`

`:.color(blue)(Slope = m = (y_2 - y_1) / (x_2 - x_1)`

`color(brown)(Slope = m = (15 - 5) / (8 - 3) = 2`
