You can put this solution on YOUR website! (2,0) is the x intercept, where the line crosses the x axis.
(0,3) is the y intercept, where the line crosses the y axis.
3x+2y=6
3(2)+2(0)=6
2 times 0 = 0 so it goes away
---------------
3(0)+2(3)=6
3 times 0 = 0 so it goes away

In the first place, if you can't spell "daughter" correctly, you probably are the daughter. Don't know what you are trying to accomplish with that story.
In the second place, an ordered pair, such as ) is not "equal" to a two-variable linear equation such as  .
Ordered pairs are elements of the solution set of such an equation. In fact there are an infinite number of ordered pairs that satisfy the given equation. In order to determine whether a particular ordered pair is a member of the solution set, substitute the first value in the ordered pair for  in the equation and substitute the second value for  in the equation. Then do the indicated arithmetic. If you end up with a true statement, in this case something that looks like  , then the ordered pair is an element of the solution set. On the other hand if you end up with an absurdity, something like  , then you know the ordered pair is NOT an element of the solution set.
