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.

B, C, E

Step-by-step explanation:

Both boundary lines are solid.

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

The boundary lines intersect.

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

(1, 3)  is a solution.

also both  boundaries intersect.

the first one is a quadrilateral (A)

the second one is a trapezoid (D)
