(12,7)

Explanation:

Plug in your given value to the x or y variable in the equation accordingly.

We are given 12 as the x value of a pint on the lin y=2x+6. So, we can plug in 12 into x.

y=2(12)+6

y=1+6

y=7

We determined that y is 7. In other words, when x equals 12, y equals 7. So if we were to plot this point and graph the equation, the point would fall on the line of the equation. Thus, it is a solution.

Whenever you are asked to complete an ordered pair with an equation, plug in your given x or y value into the equation. Whatever comes out is the value you're looking for.
