Select an ordered pair from the choices below that is a solution to the following system of inequalities: 4x + y -3 y − 2x

Question

Select an ordered pair from the choices below that is a solution to the following system of inequalities:
4x + y > -3
y − 2x < 4
 
		
(-1, 1)
 		
(0, 4)
 		
(-1, 5)
 		
(-2, 3)

Substitute each pair into the equations and see which ones get you valid equations.

anonymous · Answer

The second one is easy to resolve into:

y < 2x + 4

Can you solve from here using substitution?

anonymous · Answer

@agentx5 yes i think i can

Don't forget, if you divide or multiply by a negative # to both side of an inequality, then you shall have to flip the inequality sign going the other way, cool?  :)
