Interpret and Graph the Proportional Relationship

The Bountiful Harvest Festival awarded Kimberly and her dad first prize for their garlic fries last year, so they're making them again this year. The key to their success is using fresh potatoes.

It takes Kimberly 4 minutes to peel each potato.

There is a proportional relationship between the number Kimberly peels, x, and the amount of time (in minutes) it takes to peel that many potatoes, y.

Graph this relationship.

Select two points to draw a line.

A snail moving at a constant rate traveled a distance of 2 feet in 1/2 hour. Create a graph to represent y, the number of feet the snail traveled in x hours. Select two points on the coordinate grid that represent the situation.
