The video tutorial explains how to calculate and plot Y values based on given X values using different mathematical rules. It covers the concept of dependent variables, demonstrates plotting linear graphs with rules like Y = 2X - 6 and Y = 2X - 10, and shows how to plot a flat line graph with Y = 0X + 7. The tutorial concludes with plotting a parabola using the rule Y = X^2, emphasizing the importance of understanding dependent variables in graphing.

What does the rule Y = X - 3 imply about the relationship between X and Y?

• Y is independent of X.

• Y is always 3 more than X.

• Y is always 3 less than X.

• Y is equal to X.

If X is 5, what is the value of Y using the rule Y = X - 3?

• 3

• 2

• 5

• 8

What kind of graph is formed by the points calculated using Y = X - 3?
