b Yes, the constant of proportionality is 2.
To determine if a relationship is proportional, we need to see if the ratio between the two variables is constant. In this case, the ratio of Distance (miles) to Time (hours) is always 2. Therefore, the linear relationship is also proportional, with a constant of proportionality of 2.
A linear relationship is shown in the table.
Time (hours) 2 4 6 8
Distance (miles) 4 8 12 16
Is the linear relationship also proportional? Explain.
a No, the constant of proportionality is 2.
b Yes, the constant of proportionality is 2.
c No, there is no constant of proportionality.
d Yes, there is no constant of proportionality.
