A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service.

• C = 50h + 25

• C = 25h + 50

• C = 50h - 25

• H = 25h - 50

Which equation represents this word problem? (Hint: Your y intercept is what you start with and your slope is what is changing) Fortunata's Uber Eats driver texted her that she was 5 miles away. The driver heads towards her house with a speed of 30 miles per hour.

• y = 5x + 30

• y = 30x + 5

• 5x + 30y

• y = 5/30x

• that it is a rate of change (slope)

• that it is a total (y)

• that it is an input (x)
