Question

Which ordered pair is a solution of 6X + 7 < 21

Answer 1

Substitute 2 for x and 1 for in the inequality to verify that ordered pair satisfy the inequality or not.

`\begin{gathered} 6\cdot2+7\cdot1<21 \\ 12+7<21 \\ 19<21 \end{gathered}`

The inequality is trus so point (2,1) satisfy the inequality.

Substitute 4 for x and 1 for y in the inequality to verify that ordered pair satisfy the inequality or not.
