Question

Topic 4,: Graphing Proportional relationships.Note: A way to determine whether two quantities are proportional is to graph themon a coordinate plane. If the graph is a straight line through the origin, then the twoquanti1lies are proportional.Ex 4. Determine whether the number of calories burned is proportional to thenumber of minutes played
