$slope = - \frac{4}{5}$ $"slope "=-4/5$

Explanation:

$calculate the slope m using the gradient formula$ $"calculate the slope m using the "color(blue)"gradient formula"$

$∙ x m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $•color(white)(x)m=(y_2-y_1)/(x_2-x_1)$

$let (x_{1}, y_{1}) = (0, 4) and (x_{2}, y_{2}) = (5, 0)$ $"let "(x_1,y_1)=(0,4)" and "(x_2,y_2)=(5,0)$

$m = \frac{0 - 4}{5 - 0} = \frac{- 4}{5} = - \frac{4}{5}$ $m=(0-4)/(5-0)=(-4)/5=-4/5$
