Final answer:

To predict the value of y when x is 60 using the line of best fit, y = -173.5 + 4.83x, we calculate y = 173.3 after substituting x = 60 into the equation.

Step-by-step explanation:

Based on the provided information, we can use a line of best fit to predict values of y given a certain x value. To start, we would graph the line y = -173.5 + 4.83x by selecting the Y= key and entering the equation into Y1, then visualize it through ZOOM 9.

When we want to predict the value of y when z is 60, it seems there is a typo and it should be x instead of z. Substituting x = 60 into the equation, we get y = -173.5 + 4.83(60), which simplifies to y = 173.3. So, for an x value of 60, we predict a y value of approximately 173.3.
