a. what does the point (2, 5) represent?

b. what is the unit rate?

c. what point would you plot on the graph to indicate the unit rate?

d. what does the unit rate represent?

Explanation:

Step1: Interpret point (2,5)

The x-axis is number of tickets, y-axis is money earned. So (2,5) means 2 tickets sold earn $5.

Step2: Calculate unit rate

Unit rate = $\frac{\text{Money Earned}}{\text{Number of Tickets}}$. Use (2,5): $\frac{5}{2} = 2.5$

Step3: Find unit rate point

Unit rate is per 1 ticket, so x=1, y=2.5, point (1, 2.5)

Step4: Interpret unit rate meaning

Unit rate is money earned per 1 ticket sold.

Answer:

a. When 2 tickets are sold, the student council earns $5.
b. $\$2.50$ per ticket
c. $(1, 2.5)$
d. It represents the amount of money earned for each individual ticket sold (the cost of one ticket).
