Question

write an equation to represent the situation.
(chart: title used for pizza, y-axis number of supplies, grid with a line graph)

Explanation:

Step1: Identify slope from graph

Pick two points: $(0, 4)$ and $(2, 3)$. Slope $m = \frac{3-4}{2-0} = -\frac{1}{2} = -0.5$

Step2: Identify y-intercept

The line crosses y-axis at $(0, 4)$, so $b=4$.

Step3: Write linear equation

Use $y=mx+b$: $y = -0.5x + 4$
(Note: Based on the dropdown options shown, the structure would be $y = 4 - 0.5x$, matching the slope and intercept from the graph)

Answer:

$y = 4 - 0.5x$
