# How do you complete the ordered pair (1/2, ?) given y = 2x + 6?

$\left(\frac{1}{2} , 7\right)$

#### Explanation:

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

We are given $\frac{1}{2}$ as the x value of a pint on the lin $y = 2 x + 6$. So, we can plug in $\frac{1}{2}$ into $x$.

$y = 2 \left(\frac{1}{2}\right) + 6$

$y = 1 + 6$

$y = 7$

We determined that $y$ is $7$. In other words, when $x$ equals $\frac{1}{2}$, $y$ 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.
