Find Y-Intercept to Interpret Scatter Plots

This lesson teaches how to interpret scatter plots by identifying the Y intercept, the point where a line crosses the Y axis. It explains common mistakes, such as confusing Y and X intercepts, and uses examples like homework completion and TV watching to illustrate the concept. The lesson concludes by emphasizing the importance of understanding Y intercepts in real-world contexts.

What is the Y intercept in a graph?

• The point where the line crosses the X axis

• The point where the line crosses the Y axis

• The highest point on the graph

• The lowest point on the graph

Why is it important not to confuse the Y intercept with the X intercept?

• Because they represent the same point on the graph

• Because the Y intercept is on the Y axis and the X intercept is on the X axis

• Because they both indicate the highest point on the graph

• Because they both indicate the lowest point on the graph

In the context of a scatter plot showing homework completion and test scores, what does a Y intercept of (0,0) signify?

• A test score of 100 with no homework completed

• A test score of 0 with all homework completed

• A test score of 0 with no homework completed

• A test score of 50 with some homework completed

What does the Y intercept of (0,95) indicate in a scatter plot relating TV hours to test scores?

• A test score of 95 with maximum TV watched

• A test score of 0 with no TV watched

• A test score of 95 with no TV watched

• A test score of 50 with some TV watched

What advice is given regarding homework and TV watching?

• Do less homework and watch more TV

• Do more homework and watch more TV

• Do less homework and watch less TV

• Do more homework and watch less TV
