Slope-Intercept Form: Identify & Convert Challenges

A gym charges a monthly fee of $30 plus $5 for each class attended. What is the slope and y-intercept of the cost equation? Convert it to slope-intercept form.

• Slope: 0, Y-intercept: 30

• Slope: 5, Y-intercept: 0

• Slope: 30, Y-intercept: 5

• Slope: 5, Y-intercept: 30

A phone plan costs $25 per month plus $0.10 for each text message sent. Write the equation in slope-intercept form and identify the slope and intercept.

• y = 0.10x + 25; slope = 0.10, intercept = 25

• y = 0.10x + 0; slope = 0.10, intercept = 0

• y = 0.25x + 25; slope = 0.25, intercept = 25

• y = 25x + 0.10; slope = 25, intercept = 0.10
