A delivery service charges a base fee of $5 plus $2 for each mile driven. Write the equation in slope-intercept form and identify the slope and intercept.

• y = 5x + 2; slope = 5, intercept = 2

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

• y = 2x + 5; slope = 2, intercept = 5

A school is selling tickets for a play at $8 each. If they have a fixed cost of $200 for the venue, write the equation in slope-intercept form and identify the slope and intercept.

• y = 200x + 8; slope = 200, intercept = 8

• y = 8x + 200; slope = 8, intercept = 200

• y = 8x - 8; slope = 8, intercept = -8

• y = 8x - 200; slope = 8, intercept = -200
