Let x represent the number of hours Trenton spends studying algebra, and let y represent the number of hours he spends studying for history. Write an inequality to represent the given statements. Trenton has a total of at most 8 hours to study for both algebra and history combined. Trenton will spend at least 2 hours studying algebra.

Which of the following points lie in the solution set graphed below. Select all that apply.

• (-5, 3)

• (1, -2)

• (0, -4)

• (-8, -1)

Answer explanation

Take a look at the image attached. The 1st point is green, the 2nd point is pink, the 3rd point is blue, and the 4th point is red

Only the green and red point are in the shaded area, that means those points are apart of the solution.
