Slope-Intercept Form: Write & Identify Linear Equations

A car rental company charges a flat fee of $20 plus $0.15 per mile driven. Write the equation in slope-intercept form that represents the total cost (C) as a function of miles driven (m). What is the slope and y-intercept?

• C = 20 + 0.20m; slope = 0.20, y-intercept = 20

• C = 20 + 0.10m; slope = 0.10, y-intercept = 20

• C = 15 + 0.15m; slope = 0.15, y-intercept = 15

• C = 20 + 0.15m; slope = 0.15, y-intercept = 20

A phone plan costs $40 per month plus $0.10 for each text message sent. Write the equation in slope-intercept form for the total cost (C) based on the number of text messages (t). What do the slope and intercept represent in this context?

• C = 0.10 + 40t; Slope (40) represents the cost per text message, and the intercept (0.10) represents the base monthly cost.

• C = 40t + 0.10; Slope (40) represents the base cost, and the intercept (0.10) represents the cost per text message.

• C = 40 + 0.10t; Slope (0.10) represents the cost per text message, and the intercept (40) represents the base monthly cost.

• C = 50 + 0.05t; Slope (0.05) represents the cost per text message, and the intercept (50) represents the base monthly cost.
