• The line is only in quadrant 1

• Curvy line

• Linear and the line goes through the origin

What does a proportional relationship look like on a graph?

• A straight line that passes through the origin, (0,0).

• A line that does not pass through the origin , (0,0).

Get ready for a graph-tastic adventure! 📈 Which of these mysterious graphs holds the secret to a proportional relationship?

• A daring straight line that bravely passes through the origin, like a knight on a quest.

• A mysterious curved line that begins its journey at the origin, like a dragon's tail.

• A straight line that does not pass through the origin.

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 of potatoes 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.
