Question

y > 2x + 3
y is less than negative 3 over 2 times x minus 4

Is the point (−4, 6) included in the solution area for the system? Justify your answer mathematically.

Answer 1

okay, so we know (x,y) = (-4,6) so you just replace it in:
6>2 times (-4) +3
6> -8 +3
6>5 ( true)
so (-4,6) is the solution :)
