Determine if the graph shows a proportional relationship.
Graph with x axis labeled distance miles and y axis labeled time hours. A line begins at point 0 comma 0 and continues to the right.
Yes, it is proportional because the x-axis and y-axis are labeled correctly.
Yes, it is proportional because it is a line that intersects with the origin.
No, it is not proportional because the x-axis and y-axis are not labeled correctly.
No, it is not proportional because the line does not intersect with the origin.
Question 2(Multiple Choice Worth 2 points)
(Proportional Relationships MC)
The table shows a proportional relationship.
Workout (hours) 1 2 3
Calories Burned 190 380 570
Create a description in words for the table.
The number of calories burned is dependent on the number of hours working out. For every 190-hour workout, there is 1 calorie burned, and for every 380-hour workout, there are 2 calories burned.
The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 190 calories burned, and for a two-hour workout, there are 380 calories burned.
The number of hours working out is dependent on the number of calories burned. For every 190-hour workout, there is 1 calorie burned, and for every 380-hour workout, there are 2 calories burned.

Question 3(Multiple Choice Worth 2 points)
(Proportional Relationships MC)
Determine if the table shows a proportional relationship.
Time (hours) 0 6 12 18 24
Pay (dollars) 0 72 144 216 288
Yes, it is proportional because the ratios for dollars per hour are all equivalent to 12 dollars per hour.
Yes, it is proportional because the ratios for dollars per hour are all equivalent to 13 dollars per hour.
No, it is not proportional because 72 over 6 does not equal 216 over 18.
No, it is not proportional because 216 over 18 does not equal 288 over 24.

(Proportional Relationships MC)
The graph of a proportional relationship is shown.
graph of a line beginning at point 0 comma 0 and continuing to the right going through points 5 comma 700 and 6 comma 840 and 7 comma 980
Create a table from the graph.
x 1 2 3
y 140 280 420
x 14 28 42
y 1 2 3
x 1 2 3
y 14 28 42
x 140 280 420
y 1 2 3
Question 5(Multiple Choice Worth 2 points)
(Proportional Relationships MC)
Three different recipes each make a different number of cookies and require a different amount of flour.
Recipe 1: 3 dozen cookies; 4.5 cups of flour
Recipe 2: 4 dozen cookies; 6 cups of flour
Recipe 3: 5 dozen cookies; 7.5 cups of flour
Determine if the three recipes use a proportional amount of flour.
Yes, it is proportional because the cookies increase by 1.5 dozen for every 1 cup of flour.
Yes, it is proportional because the ratios between the number of cookies and cups of flour are all equivalent.
No, it is not proportional because the number of cookies and cups of flour could not be zero at the same time.
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
Question 6(Multiple Choice Worth 2 points)
(Proportional Relationships MC)
Determine if the table shows a proportional relationship.
x 42.5 29.2 69.4
y 21.25 14.6 34.7
Yes, it is proportional because the ratios for y over x are all equivalent to one half.
Yes, it is proportional because the ratios for y over x are all equivalent to one third.
No, it is not proportional because 21.25 over 42.5 is not equal to 29.2 over 14.6.
No, it is not proportional because 42.5 over 21.25 is not equal to 34.7 over 69.4.
Question 7(Multiple Choice Worth 2 points)
(Proportional Relationships MC)
A group of hikers tracked how long it took to hike a 20-mile trail. They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours.
Determine if the relationship between the hikers' distance and time is proportional.
Yes, it is proportional because the ratios for miles per hour are all equivalent to 1.25 miles per hour.
Yes, it is proportional because the ratios for miles per hour are all equivalent to 0.8 miles per hour.
No, it is not proportional because 3.75 miles in 3 hours is not equivalent to 7.5 miles in 6 hours.
No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
