Question

Can someone help me?
which point is a solution to the system?
y>3x+8
y≤-1/2x+4

Answers:

(2,5)
(1,-1)
(-4,2)
(-2,7)

Answer 1

Try each point in both inequalities. The point that satisfies both inequalities is a solution to the system of inequalities.

Answer 2

I will use choice A as an example.
Plug in (2, 5) in the first inequality:
y > 3x + 8
5 > 3(2) + 8
5 > 6 + 8
5 > 14
This is false, so point (2, 5) does not satisfy the first inequality. You can stop choice A now because since it does not satisfy the first inequality, it obviously will not satisfy both inequalities.

Now try the point in choice B in both inequalities, and so on.
