(1/2, 7)(12,7)

Explanation:

Plug in your given value to the xx or yy variable in the equation accordingly.

We are given 1/212 as the x value of a pint on the lin y=2x+6y=2x+6. So, we can plug in 1/212 into xx.

y = 2(1/2)+6y=2(12)+6

y= 1 + 6y=1+6

y = 7y=7

We determined that yy is 77. In other words, when xx equals 1/212, yy equals 77. 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 xx or yy value into the equation. Whatever comes out is the value you're looking for.
