Write an equation in slope-intercept form with a slope of -2/3 and goes through the point (3,4).

Hint* use y = mx + b to find any missing measures!

Write an equation in slope-intercept form of the graph.

What is the initial cost and cost per hour?

• initial cost = $97

  cost per hour = $32

• initial cost = $32

  cost per hour = $97

• initial cost = $65

  cost per hour = $32

• initial cost = $32

  cost per hour = $65
