Determining Unit Rate from Proportional Graphs

The video tutorial explores the concept of slope in proportional graphs, emphasizing unit rates. It begins with an introduction to proportional graphs and unit rates, followed by examples to illustrate unit rates using apples and drinks. The tutorial then explains different ways to represent slope, including fractions, decimals, and verbal descriptions. It demonstrates how to find slope from graph points, using examples like the cost of lunches and pages read per minute. Finally, it covers matching unit rates to graph slopes, using a babysitting example to illustrate the process.

What is a unit rate in the context of proportional graphs?

• The slope of the graph

• The intercept of the graph

• The area under the graph

• The maximum value on the graph

How do you calculate the unit rate for apples given the price for a specific quantity?

• Add the cost to the number of apples

• Divide the total cost by the number of apples

• Subtract the number of apples from the total cost

• Multiply the number of apples by the total cost

What does a unit rate of $2.50 represent in the context of buying drinks?

• The cost of one drink

• The cost of eight drinks

• The cost of sixteen drinks

• The cost of two drinks

How can slope be represented in a graph?

• As a fraction

• As a percentage

• As a sum

• As a product

What does a slope of 6/1 indicate in a practical scenario?

• $6 per two lunches

• $6 per lunch

• $12 per two lunches

• $3 per lunch

What is the unit rate if 3 pages are read in 2 minutes?

• 1.5 pages per minute

• 2 pages per minute

• 3 pages per minute

• 0.75 pages per minute

What does a unit rate of 1.5 pages per minute imply?

• 1.5 minutes per page

• 0.75 pages per minute

• 1.5 pages per minute

• 2 pages per minute

If Britney earns $105 for 7 hours of babysitting, what is her hourly rate?

• $15 per hour

• $7.50 per hour

• $21 per hour

• $10.50 per hour

How do you find the correct graph for a given unit rate?

• By matching the highest point on the graph

• By finding the slope that matches the unit rate

• By choosing the graph with the most data points

• By selecting the graph with the steepest slope

What does a slope of zero indicate about a graph?

• The graph is non-linear

• The graph is increasing

• The graph is decreasing

• The graph is constant
