Which statements are true about the graph of y ≤ 3x + 1 and y ≥ –x + 2? check all that apply. the slope of one boundary line is 2. both boundary lines are solid. a solution to the system is (1, 3). both inequalities are shaded below the boundary lines. the boundary lines intersect.

Both boundary line are solid because of the ≤ and ≥  signs.

(1, 3)  is a solution.

also both  boundaries intersect.

B, C, E

Step-by-step explanation:

Both boundary lines are solid.

A solution to the system is (1, 3).

The boundary lines intersect.

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.
