For a linear equation like this there will always be infinitely many solutions if you let x and y be any real number. So you can just pick any x and find the corresponding y. Take for exmaple x=1 then we get
-1+2y=8
2y=9
y=9/2=4.5 so an ordered pair that satifies your equation is (x,y)=(1,9/2).
Now you can go on and find more.

If you posted the actual question then yes, but it won't load on my computer, so, no.
Trapezoid: four sides, two of which are parallel.
Opposite number or additive inverse of any number (n) is a number which, if added to n, results in 0, the identity element of addition. You can say that the opposite number of a number, is the negative version of the positive number. This is what the opposite of 4 is or the opposite of -4
