A computer technician charges a fee of $50 to diagnose a problem and $70 per hour to fix it. Write an equation in slope-intercept form to represent this situation. Identify the initial value and the rate of change.

Question

1.The initial value is $120.
2.The initial value if $70 and the rate of change is $50.
3.The rate of change is $120.
4.The initial value is $50 and the rate of change is $70.

Answer 1

The correct answer is:

5. The equation in slope-intercept form is: y = 70x + 50

Where:
- y represents the total cost
- x represents the number of hours
- 70 is the rate of change (cost per hour)
- 50 is the initial value (diagnostic fee)

Therefore, the initial value is $50 and the rate of change is $70.
