Someone's homework?
y=0, x=-2
y=2, x=-4
y=4, x=-5
I am sorry but the question is incomplete. You have not mentioned the ordered pairs and the equation is incomplete as well.
There are infinitely many ordered pairs. One of these is (0, 0).
1,6 2,12 3,18 4,24 5,30
There are an infinite number of ordered pairs that satisfy the equation.
Use this cordinate ,find the other cordinate that makes the ordered pair a solution of the given equation: x+4y=7,(_,3)

That depends on the equation.
Graph of an equation.
I am sorry but the question is incomplete. You have not mentioned the ordered pairs and the equation is incomplete as well.
Select any three values of x in the domain of the equation. Solve the equation at these three points for the other variable, y. Then each (x, y) will be an ordered pair that is a solution of the equation.
It is not. It is called a LINEAR equation. This is because the word linear refers to a line and, if the solutions of the equation, in the form of ordered pairs (x,y), were plotted on a Cartesian plane, they would all lie on a straight line.
None of them.None of them.None of them.None of them.

They are all the pairs you make where (x = any number) and (y = 4).
x = 4 and y = 7
There are infinitely many ordered pairs - each pair representing a different point on the infinite line described by the equation.
There are infinitely many ordered pairs. One of these is (0, 0).
