Question

card 14
a slope:
b (graph with y-axis labeled dollars, x-axis labeled comics, line from (0,20) to (5,0))

Explanation:

Step1: Identify two points

The line passes through \((0, 20)\) (y-intercept) and \((5, 0)\) (x-intercept).

Step2: Use slope formula

Slope \(m = \frac{y_2 - y_1}{x_2 - x_1}\). Substitute \((x_1, y_1) = (0, 20)\) and \((x_2, y_2) = (5, 0)\):
\(m = \frac{0 - 20}{5 - 0} = \frac{-20}{5} = -4\).

Answer:

\(-4\)
