What is the slope of a line passing through (3,4) and (5,8)?

1 Answer

Mar 22, 2016

The slope $= 2$ $color(blue)(=2$

Explanation:

The coordinates are :
$(3, 4) = x_{1}, y_{1}$ $(3,4) = color(blue)(x_1, y_1$
$(5, 8) = x_{2}, y_{2}$ $(5,8) = color(blue)(x_2, y_2$

The slope is calculated using formula:
Slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $= color(blue)((y_2 -y_1)/(x_2- x_1)$

$= \frac{8 - 4}{5 - 3}$ $= (8-4) / (5-3)$

$= \frac{4}{2}$ $= (4) / (2)$

$= 2$ $color(blue)(=2$
