The slope $= \frac{5}{3}$ $=5/3$

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

$(5, 4) = x_{2}, y_{2}$ $(5,4) = color(blue)(x_2,y_2$

The slope is calculated using formula:

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

$= \frac{4 - 9}{5 - 8}$ $= (4-9)/(5-8$

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

$= \frac{5}{3}$ $= 5/3$

What is the slope of the line passing through the following points: (8,9) , (5,4)(8,9),(5,4)(8,9) , (5,4)?
