Tocheck:Whether the given relationship is proportional or not with the help of graph on coordinate plane.

Answer to Problem 2GP
The given relationship is proportional as the line joining all the points is a straight line that passes through the origin.
Explanation of Solution
Given information:The following relationship is given:
Number of Gallons | ||||
Number of Quarts |
Calculation:
A relationship is proportional if the line joining the points of relationship is a straight line passing through the origin.
Draw the graph of the line joining the given points on the coordinate plane as number of gallons on
Figure(1)
As observed from graph, the line joining all the points is a straight line that passes through the origin.
Therefore, the given relationship is proportional.
