Question

a bakery earns \\$10 for selling 5 cookies.
\\\frac{\\$10}{\text{5 cookies}} = \frac{\\$2}{\text{1 cookie}}\\
which graph describes this ratio?
hint: use the unit rate as the slope.

Explanation:

Identify the unit rate as slope

$$ \text{Slope } (m) = \frac{\$10}{5\text{ cookies}} = \$2\text{ per cookie} $$

Determine the linear equation

$$ y = 2x $$

The first graph passes through \((1, 2)\), \((2, 4)\), and \((3, 6)\).

Answer:

• (A) The first graph, which passes through (1, 2), (2, 4), and (3, 6) (Correct answer)
• (B) The second graph, which passes through (2, 1), (4, 2), and (6, 3)
• (C) The third graph, which passes through (1, 5)
