Using the line of the best fit, the predicted student's score in English test is 48

<h3>How to determine the student's score in English?</h3>

Mathematics score = 60

The scores in English tests are plotted on the y-axis.

On the given graph, we have:

This in other words means that the student's score in English test is 48
