Question

2x + 5y = 10; (1, 2), (6, 1)is each ordered pair a solution of the inequality

Answer 1

The equation is:

`2x+5y=10`

So we try for the coordinate (1,2) so:

`\begin{gathered} 2(1)+5(2)=10 \\ 2+10=10 \\ 12\\e10 \end{gathered}`

So this is not an ordered pair

For (6,1)

`\begin{gathered} 2(6)+5(1)=10 \\ 12+5=10 \\ 17\\e10 \end{gathered}`

So non of them is an ordered pair
