GRAPHING PROPORTIONAL RELATIONSHIPS
11.Determine whether the relationship between the total amount Regina earned and the number of lawns she mowed is proportional by graphing on the coordinate plane. Choose the correct answer.
Regina’s Earnings
Lawns Mowed / Total Earnings ($)
1 / 14
2 / 28
3 / 42
4 / 56
a. / No, because the graph of the line connecting the ordered pairs passes through the origin.
b. / No, because the graph of the line connecting the ordered pairs does not pass through the origin.
c. / Yes, because the graph of the line connecting the ordered pairs passes through the origin.
d. / Yes, because the graph of the line connecting the ordered pairs does not pass through the origin.
12.Determine whether the relationship between the total number of coins John collected and the number of weeks he has been collecting them is proportional by graphing on the coordinate plane. Choose the correct answer.
John’s Coin Collection
Time Collecting (wk) / Total Coins Collected
2 / 35
4 / 55
6 / 75
8 / 95
a. / No, because the graph of the line connecting the ordered pairs passes through the origin.
b. / No, because the graph of the line connecting the ordered pairs does not pass through the origin.
c. / Yes, because the graph of the line connecting the ordered pairs passes through the origin.
d. / Yes, because the graph of the line connecting the ordered pairs does not pass through the origin.
