How do you find the slope of a line that passes through the points y-intercept (0,8) and the x intercept (-2,0)?

The slope is $m = 4$ $m = 4$

Explanation:

The equation for the slope based upon two points is
$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $m = (y_2-y_1)/(x_2 - x_1)$

For the points $(0, 8) & (- 2, 0)$ $(0,8) & (-2,0)$

$x_{1} = 0$ $x_1 = 0$
$y_{1} = 8$ $y_1 = 8$
$x_{2} = - 2$ $x_2 = -2$
$y_{2} = 0$ $y_2 = 0$

$m = \frac{0 - 8}{- 2 - 0}$ $m = (0-8)/(-2-0)$

$m = - \frac{8}{- 2}$ $m = -8/-2$

$m = 4$ $m = 4$
