How do you find the slope of (4,8) , (8,11)?

1 Answer

May 1, 2016

The slope $= \frac{3}{4}$ $= (3 ) / (4)$

Explanation:

$(4, 8) = x_{1}, y_{1}$ $(4,8) = color(blue)(x_1 , y_1$

$(8, 11) = x_{2}, y_{2}$ $(8 , 11) = color(blue)(x_2 , y _ 2$

The slope is calculated using formula:
Slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $= color(blue)((y_2 - y_1) / (x_2 - x _1)$

$= \frac{11 - 8}{8 - 4}$ $= (11 - 8 ) / (8 -4)$

$= \frac{3}{4}$ $= (3 ) / (4)$
