Mastering Slope-Intercept: Identify & Convert Equations

A local gym has a membership fee of $30 per month. If a member also pays a one-time registration fee of $100, express the total cost as a linear equation in slope-intercept form. What are the slope and intercept?

• Slope: 0, Intercept: 100

• Slope: 30, Intercept: 0

• Slope: 30, Intercept: 100

• Slope: 100, Intercept: 30

A delivery service charges a base fee of $15 plus $2 for each mile driven. Convert this equation from standard form to slope-intercept form and identify the slope and intercept.

• Slope: 2, Y-intercept: 10

• Slope: 0, Y-intercept: 15

• Slope: 2, Y-intercept: 15

• Slope: 15, Y-intercept: 2

A school is planning a fundraiser. They will earn $5 for each ticket sold, plus a $200 initial donation. Write the equation in slope-intercept form and identify the slope and y-intercept.

• y = 5x + 200; slope = 5, y-intercept = 200

• y = 5x + 300; slope = 5, y-intercept = 300

• y = 5x + 100; slope = 5, y-intercept = 100

• y = 10x + 200; slope = 10, y-intercept = 200
