WK 21 Mon Proportional given a graph or table
 1. From the graph, a straight line passing through the origin.2. From the table, the Constant of Proportionality are all the same. Which means the ratio comparing y-value to thex-value; that is y-value divided by x-value.Data is proportional if:Study the following slides and decide if data is proportional based on reasoning. Not proportional because the line does not passthrough the origin. Not proportional because the line is not straight. Proportional because the straight line does passthrough the origin.
