Answer:


y=35x+200

The slope is 35 and it means the technician earns $35 per hour.

Explanation:

The technician finds that

  • when he works 55 hours during the month, he earns $2,125;
  • when he works 30 hours, he earns $1,250.

Let

x = number of hours worked

y = amount of money earned

Find the slope of the linear equation:


(2,125-1,250)/(55-30)=(875)/(25)=35

Equation of the linear function:


y-1,250=35(x-30)\\ \\y=35x-1,050+1,250\\ \\y=35x+200

The slope is 35 and it means the technician earns $35 per hour.
