Graphing Proportional Relationships and Slope Concepts

The video tutorial explains how to graph real-world proportional relationships using a practice problem involving Susie's earnings as a cashier. It covers identifying independent and dependent variables, creating ordered pairs, drawing and labeling the graph, plotting points, and understanding the slope as the unit rate.

What is the independent variable in Susie's job scenario?

• The days Susie works

• The hours Susie worked

• The amount of money Susie earns

• The number of customers Susie serves

Which variable is affected by the other in Susie's job scenario?

• The days Susie works

• The number of customers Susie serves

• The amount of money Susie earns

• The hours Susie worked

What is the first step in creating a graph for Susie's earnings?

• Drawing the line

• Identifying the variables

• Labeling the axes

• Plotting the points

How much does Susie earn after working two hours?

• $27

• $18

• $9

• $36

What should be the title of the graph representing Susie's earnings?

• Susie's Work Hours

• Susie's Earnings

• Susie's Job

• Susie's Paycheck

What interval should be used for the y-axis in Susie's graph?

• Counting by 1

• Counting by 5

• Counting by 9

• Counting by 10

Where should the first data point (0,0) be plotted on the graph?

• At (0,1)

• At (1,1)

• At the origin

• At (1,0)

What is the ordered pair for Susie's earnings after working three hours?

• (3, 27)

• (2, 18)

• (3, 18)

• (2, 27)

What does the slope of the graph represent in Susie's job scenario?

• The total earnings

• The amount of money earned per hour

• The number of hours worked

• The number of customers served

What is the unit rate in Susie's job scenario?

• $36 per hour

• $9 per hour
