Q12. - Algebra 2

Question

For Exercises 10-12, use the graph that shows how much Americans spent on doctors’ visits in some recent years. 

12. Compare your prediction to the one given in the graph.

Step-by-Step Solution

Answer

The value predicted by the equation is lower than the given in the graph.

Step-1 – Concept of prediction equation.

Prediction equation – An equation of line of fit is often called a prediction equation

Step-2 – Predicted value from the equation.

From the equation we know that the predicted value of amount spent on doctor’s visit $1077

And the actual value $1,172 from the graph.

 $\begin{array}{l}1172-1077\\ =95\end{array}$

Step-3 – Compare the prediction.

The value predicted by the equation is lower than the given in the graph.
