The table represents some points on the graph of a linear function.

Which function represents the same relationship?

• h(x) = -3x - 10.5

• h(x) = -x - 3.5

• h(x) = 3x - 10.5

• h(x) = x - 3.5

The tables of ordered pairs represent some points on the graphs of lines f and g.

Which system of equations represents lines f and g?

• y = 1.75x + 3.5

  y = -4x - 8

• y = 1.75x + 3.5

  y = -4x - 2

• y = 3.5x + 1.75

  y = -4x - 8

• y = 3.5x + 1.75

  y = -4x - 2

The graph shows the linear relationship between the maximum area in square feet that can be painted and the number of gallons of paint used.

• 200 sq ft/gal

• 400 sq ft/gal

A lifeguard earns $320 per week for working 40 hours plus $12 per hour worked over 40 hours. A lifeguard can work a maximum of 60 hours per week.
