the graph shows the number of quarts picked the graph shows the number of quarts picked and amount of money paid by different customers

Answer:
Step-by-step explanation:
Part A
Since, line shown in the graph passes through origin (0, 0), relation between number of quarts picked (Q) and amount of money paid (M) will be proportional.
M ∝ Q
M = kQ [k = proportionality constant]
k = Slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, line passes through two points (1, 3.5) and (2, 7),
k = [tex]\frac{7-3.5}{2-1}[/tex] = 3.5
Therefore, M = 3.5Q
This relation states that "For each number of quarts picked, $3.5 is to be paid"
Part B
Equation that represents the proportional relation,
y = 3.5x
Or Amount of money paid = 3.5(Number of quarts picked)
