3. A bike rental shop charges a flat fee of $10 plus $2 per hour. Write the equation in slope-intercept form and identify the slope and y-intercept.

• y = 2x - 10; slope = 2, y-intercept = -10

• y = 2x + 10; slope = 2, y-intercept = 10

• y = 10x + 2; slope = 10, y-intercept = 2

• y = 5x + 10; slope = 5, y-intercept = 10
