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

The coordinates are:
$(9, 8) = x_{1}, y_{1}$ $( 9 , 8 ) = color(blue)(x_1,y_1$

$(3, 0) = x_{2}, y_{2}$ $( 3 , 0 ) = color(blue)(x_2,y_2$

The slope is calculated using formula:

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

$= \frac{0 - 8}{3 - 9}$ $= ( 0 - 8) / ( 3 - 9 )$

$= \frac{- 8}{- 6}$ $= ( - 8) / ( -6)$

$= \frac{8}{6}$ $= 8 / 6$

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