Graphing Proportional Relationships Using a Table

This video tutorial explains how to graph proportional relationships using tables and coordinate planes. It covers the basics of proportions, the coordinate plane, and plotting points. The tutorial uses a real-life example of babysitting earnings to illustrate the concept. It also addresses common mistakes students make when graphing proportional relationships, emphasizing the importance of correctly identifying the x and y axes.

What is a proportion?

• A statement showing two ratios are equal through addition

• A statement showing two ratios are equal through division

• A statement showing two ratios are equal through subtraction

• A statement showing two ratios are equal through multiplication

How do you find the point (3, 4) on a coordinate plane?

• Move 4 spaces right and 3 spaces up

• Move 4 spaces up and 3 spaces right

• Move 3 spaces right and 4 spaces up

• Move 3 spaces up and 4 spaces right

What is the origin on a coordinate plane?

• The point where x is 1 and y is 1

• The point where x is 0 and y is 0

• The point where x is 0 and y is 1

• The point where x is 1 and y is 0

When graphing a proportional relationship, which axis represents the input?

• The z-axis
