Question

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

Answer 1

`(1/2, 7)`

Explanation:

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

We are given `1/2` as the x value of a pint on the lin `y=2x+6`. So, we can plug in `1/2` into `x`.

`y = 2(1/2)+6`

`y= 1 + 6`

`y = 7`

We determined that `y` is `7`. In other words, when `x` equals `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.
