I cannot find the correct two solutions for this equation. The first one I came up with was (0,3).

You can't find two solutions because it isn't a quadratic equation (ax^2+bx=c) because the "ax" does not have "squared".
It is a Linear equation (y=mx+b) in which the y-intercept (b) is 3 and the slope (m) is 1/2. (y=1/2x+3)
The point on the y-axis is (0,3), and
the point on the x-axis is (-6,0)
Because this is a straight line, not a curved one, you can't have two points on the same axis.
Now, that's just basic information you should know.
To find ANY solution to -x+2y=6, plug in any number for x or y and figure out the opposite (x or y).
Some examples are (-4,1), (-2, 2), (0, 3), (2, 4), etc.
Good Luck!

There is nothing called two solutions for this equation, since it is a linear one. All real numbers can fit in this equation, just put any number instead of x or y, and then solve the equation. For example take x=10, so the equation becomes -10 + 2y = 6
so 2 y is 16 and so y is 8, the coordinates are then (10, 8), and so on.

Just substitute any number in the place of x and find y then that will be your odered pair.
For example, substitute x = 2 then the equation becomes as follows
-2 +2y = 6 gives y = 4.
So the other point is (2,4)
In the same way you can have many solutions for each number you substitute.
Hope you understand this.

Why two, you can find any number of solutions to draw a graph
put x = 2, you get y = 4, ie, (2,4) is a point
pur x = 4, you get y = 5, i.e (4,5) is a point
put x = 6, you get y = 6, i.e.(6,6) is a point
join all the above points and you get a straight line graph

The graph is of a straight line, so it will cross each axis at exactly one point. You need two points to draw a line, and it is convenient to let the axis crossings be these points. This leads to the following:
- If x = 0, then 2y = 6, so y = 3, and your first point is (0, 3).
- If y = 0, then -x = 6, so x = -6 and your second point is (-6, 0).

This is a line equation, if u put any number instead of X then u will have a number for y, for example , choose x=1 then u c 2y=7 and y=3.5, some other quantities are: ( 2,4 ) , ( 3,4.5 ), ( -1,2.5) , ..

2y=6
y=6/2
y=3
I'm not sure how to solve for the x though.
?-x+2(3)=6
?-x=1??????

(2,4) works too.
