Predict The cost of a school photo package includes $40 for the photo shoot, plus the
number of photos ordered multiplied by the price per photo. Is this situation defined by
a linear function? Predict the answer and then write and graph an equation on anothe
sheet of paper to check your prediction. You can use $2.50 or any other value as the cos
per photo

1. Linear; 2. C = 2.50x + 40  

Step-by-step explanation:

1. Prediction

Yes, it is a linear function, because each additional photo adds the same amount to the cost.

2. Equation

         Let C = the cost of the photo package

         and x = the number of photos

Then 2.50x = the cost of the photos

    And $40 = cost of photo shoot

      Then C = 2.50x + 40

The figure below shows that the graph of your equation is a straight line.
