Unit rate of change: ________________________
Linear? __________________________
Dependent Variable: _y = Total dollar amount earned per hour
Independent Variable: __x= # of hours worked
Starting Point: ____ __________________
Equation: ________________________________
Check
unit rate is $/hr, so divide money by time
since (30-10)/(4-0) = (50-30)/(8-4) it is linear
since we have established they are proportional, they start at (0,0)
