In the graph is shown: x-axis is the hours that student spend studying for the test and y-axis is a grade obtained by student. The best fit equation is y=3.75x+52.5.
If student spend 0 hours, then x=0 and y=3.75*0+52,5=52.5. It is that the student most likely earn <span>grade of 52.5 in the test. </span>
