Non-Proportional - Graph does not cross (0,0) and (y=mx + b) has “b” value *You will find these situations have a starting amount like an extra fee, starting height or weight, etc.

Question

Andrew does computer repairs in his home. He charges a $10 fee to analyze the problem, plus an hourly rate of $25 for his labor. Create a table, graph and equation that represent this situation.

Answer 1

Table:
| Hours of Labor | Total Cost ($) |
|---------------|-----------------|
| 0 | 10 |
| 1 | 35 |
| 2 | 60 |
| 3 | 85 |
| 4 | 110 |

Equation: y = 25x + 10

Graph:
The graph will be a straight line that starts at (0,10) and has a slope of 25, representing the $25 hourly rate.
