Linear Graphs: Interpret & Solve Real-World Problems

A company tracks its profits over time, and the graph shows a linear increase. If the profit after 3 months is $500 and increases by $200 each month, what is the equation representing the profit in terms of months?

• Profit = 200m - 100

• Profit = 300m - 100

• Profit = 500 + 200m

• Profit = 200m + 100

The graph of a linear function shows the distance traveled by a car over time. If the car travels 60 miles in 1 hour, what is the equation of the line representing the distance in terms of time?

• y = 30x

• y = 60 + x

• y = 60x

• y = 60x + 10

A school is planning a fundraiser, and the graph shows the amount of money raised over time. If they raised $300 in the first week and $150 each subsequent week, what is the equation for the total amount raised after 'w' weeks?

• Total = 300w

• Total = 150w + 300

• Total = 150w - 150

• Total = 150w + 150

A store's sales are represented by a linear graph. If the sales were $800 in the first month and increased by $100 each month, what is the equation for the sales after 'm' months?

• y = 800 + 100m

• y = 900 + 100m

• y = 100m + 8000

• y = 800 - 100m

A farmer measures the growth of his crops, and the graph shows a linear trend. If the crop yield was 200 pounds at the start and increases by 50 pounds each week, what is the equation for the yield after 'w' weeks?

• Y = 200 - 50w

• Y = 50w

• Y = 200 + 25w

• Y = 200 + 50w

A tech company monitors its website traffic, and the graph shows a linear increase. If the traffic was 1,000 visits in the first month and increases by 200 visits each month, what is the equation for the number of visits after 'm' months?

• v = 1000 + 200m

• v = 800 + 250m

• v = 1000 - 200m

• v = 1200 + 150m
