Which statements are true about the graph of y s 3x + 1 and y2 -x + 2? Check all that apply. The slope of one boundary line is 2.
Both boundary lines are solid.
O A solution to the system is (1, 3).
Both inequalities are shaded below the boundary lines.
The boundary lines intersect.

- the answer is the 2nd, 3rd and 5th answer choices. but i don’t know why.
