Question

Jada earns twice as much money per hour as Diego. Diego earns twice as much money per hour as lin. Select all the graphs that could represent how much Jada, diego, and lin earn for different amounts of time worked.

Answer 1

• 1 and 3

Explanation:

Let functions be

• Jada = f(j)
• Diego = f(d)
• Lin = f(l)

As per given ratios:

• f(d) = 2f(l)
• f(j) = 2f(d) ⇒ f(j) = 4f(l)

The smallest slope belongs to f(l), greater - f(d), the greatest - f(j)

Possible graphs reflecting the functions are graph 1 and graph 3
