Given the equation:

y = 12x + 40

Where x represents the number of hours and y represents the number of points the student should earn.

To find the correct statement substitute the number of hours and points given for x and y respectively. If the left hand side of the equation equals the right hand side then the statement is the true.

We have:

1. A student who studies for 3 hours should earn about 76 points.

x = 3

y = 76

Substitute 3 for x and 76 for y.

y = 12x + 40

76 = 12(3) + 40

76 = 36 + 40

76 = 76

This statement is true.
