Question 1079317: Hello, I have to find three ordered pairs, & graph them on a coordinate plane, for the following equation:
2x-y=3. I have to table the ordered pairs in x and y columns.
Do I convert the equation to: y=2x-3 ? Or do I convert the equation to: y=2x+3 ? Or do I need to convert the 2x to a negative 2x ?
Please help?

You can put this solution on YOUR website!
You don't really need to change the equation.
Suppose you want the ordered pair ( x1, 0 )
Just make +y%5B1%5D+=+0+ and find +x%5B1%5D+
+2x%5B1%5D+-+0+=+3+
+2x%5B1%5D+=+3+
+x%5B1%5D+=+3%2F2+
So now you have the ordered pair:
( x1, y1 ) = ( 3/2 , 0 )
----------------------------------
Suppose you want the ordered pair ( 1 , y2 )
Make +x%5B2%5D+=+1+ and find +y%5B2%5D+
+2%2A1+-+y%5B2%5D+=+3+
+2+-+y%5B2%5D+=+3+
+-y%5B2%5D+=+1+
+y%5B2%5D+=+-1+
So now you have the ordered pair:
( x2, y2 ) = ( 1 , -1 )
---------------------------------
You can create as many ordered pairs as you want this way
