A system of equations is shown.
y=32x−6
3y−2x=9
How many solutions does the system have, and why?
There are no solutions because the slopes and y-intercepts are the same.
There are infinitely many solutions because of the slopes and y-intercepts are the same.
There are no solutions because the slopes are the same and the y-intercepts are different.
There are infinitely many solutions because the slopes are the same and the y-intercepts
are different.

Jonathan goes to a baseball game. At the beginning of each of the nine innings in the game, he estimates the percentage of seats in his section that are full. He makes a graph to show the relationship between the inning, x, and the percentage of seats in his section that are full, y.
Which statement about the section in which Jonathan sits at the baseball game is most
likely true?
Most of the fans left during the eighth inning.
The greatest number of fans arrived.
There was at least one point during the game in which Jonathan's section was 100% full.
The same seats were full at the beginning of the third inning as at the beginning of the sixth inning.

Lucy has a lemonade stand. The table shows Lucy’s profits when she sells different amounts of lemonade.
Which equation could Lucy use to determine her profit, y, when she sells x cups of lemonade?
y = x - 5
y = 5x - 1
y = x
y = x + 5
1The equation shows the average cost, y, in dollars, of electricity per kilowatt hour (kWh) used, x, for homes in the state of Missouri in 2011.

Mr. Rose surveyed his students about the amounts of time they spent studying for his final exam and their final exam scores. He graphed the results on a coordinate plane. Which graph shows the best approximation of the line of best fit for Mr. Rose’s data?
Function 1 is shown on the coordinate plane. Function 2 is represented by the equation y = 3x + 1. Which statement about the rate of change is correct?
Function 1 has a grater rate of change.
Function 2 has a greater rate of change.
Both functions have the same rate of change.
There is not enough information to determine which function has the greater rate of change.

Barry and Omar each sell potato salad in their sandwich shops. Barry uses the graph shown to determine the total cost for different amounts of potato salad.
Omar uses the equation y = 2.89x to determine the total cost, y, in dollars, for x pounds of potato salad. Which statement about the cost of potato salad at Barry’s and Omar’s sandwich shops is true?
The cost per pound at Barry's sandwich shop is less than the cost per pound at Omar's sandwich shop.
The cost per pound at Omar's sandwich shop is less than the cost per pound at Barry's sandwich shop.
The cost per pound at the cheaper sandwich shop depends on how many pounds of potato salad a customer purchases.
It is impossible to determine which sandwich shop charges less per pound based on the given information.

Henry surveys 80 people. He asks each person two questions:
• Have you ever taken a taxi?
• Have you ever visited another state?
He makes the two-way table to show the results of his survey.
Complete each sentence with “more likely”, “less likely”, or “equally as likely” based on the
results from Henry’s survey.
A random person from Henry’s survey is __________________ to have taken a taxi than to
have not taken a taxi.
A random person from Henry’s survey who has taken a taxi is __________________ to have
visited another state than to have not visited another state.
A random person from Henry’s survey who has not visited another state is
__________________ to have taken a taxi than to have not taken a taxi.
