#(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.
