That's what algebra is for. Pair up the equations to fin the intersections:
3x+4y = 12
5x+6y = 30
x = -16 and y = 15
and likewise for the others. No eyeballing needed.
Find the coordinates of any vertices formed. 3x + 4y ≥ 12, 5x + 6y ≤ 30, and 1 ≤ x ≤ 3.
I tried graphing this, which formed a parallelogram, but it was hard to find eyeball vertices.

Shouldn't it have 4 points due to 4 vertices?
