Is this ordered pair a solution to the inequality?<br> (1, 3)<br> 5x+y&lt;-3<br> A.)No<br> B.)Yes
max2010maxim [7]
(1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality

5*x + y < -3
5*1 + y < -3 ... replace x with 1
5*1 + 3 < -3 ... replace y with 3
5 + 3 < -3
8 < -3

This is false. The number 8 is NOT smaller than -3. 

So (1,3) is NOT a solution

Answer: Choice A) No
