If you were to graph both of these scenarios on the coordinate plane, the first graph would be proportional and the second non proportional.

How would you transform the first graph to make it become a non proportional graph with the same y-intercept as the second graph?

To transform the first graph to make it non-proportional with the same y-intercept as the second graph, you would move the graph right by 20 units, up by 20 units, and left by 1 unit. This will shift the graph horizontally, vertically, and slightly to the left.

To transform the first graph and make it non-proportional while maintaining the same y-intercept as the second graph, you would need to adjust the x-values. Specifically, you would need to move each point on the first graph to the right by 1 unit.

Here are the steps to transform the first graph:

1. Identify the points on the first graph. Let's say one of the points is (0, 12).

2. Move each point on the first graph to the right by 1 unit. In this case, (0, 12) would become (1, 12).

3. Repeat this process for all the points on the first graph.

After performing this transformation, the first graph would become non-proportional while maintaining the same y-intercept as the second graph.
