Question

Is (7, 9) a solution to the inequality y>2x+1?​

Answer 1

no and here’s why

you input the number into your inequality

9>2(7)+1

when you simplify that you get

9>15

and 9 is NOT greater than 15 so no it is not a solution to the inequality

Answer 2

Answer:

On my calculator, it says “nothing further can be done” meaning nothing else can prove the inequality.

Even if you graph it, the solution wouldn’t be (7,9)
