Question

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.
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 Worked | Total Cost
0 | $10
1 | $35
2 | $60
3 | $85

Equation: y = 25x + 10

Graph:

(Imagine a graph with the x-axis representing hours worked and the y-axis representing total cost. The graph will start at the point (0,10) and then will have a straight line with a slope of 25, representing the hourly rate, going upwards.)
