The slope $= \frac{8}{5}$ $= 8/ 5$

$(- 7, - 4) = x_{1}, y_{1}$ $(-7,-4) = color(blue)(x_1 , y _ 1 )$

$(- 2, 4) = x_{2}, y_{2}$ $(-2,4) = color(blue)(x_2 , y _2 )$

The slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $= color(blue)((y_2- y_1) / (x_2 - x_1)$

$= \frac{4 - (- 4)}{- 2 - (- 7)}$ $= (4 - (-4)) / (-2-(-7))$

$= \frac{4 + 4}{- 2 + 7}$ $= (4 + 4) / (-2 + 7)$

$= \frac{8}{5}$ $= 8/ 5$

What is the slope of the line passing through the following points: (-7, -4) , (-2, 4)(−7,−4),(−2,4) (-7, -4) , (-2, 4)?
