There are an infinite number of ordered pairs that satisfy the equation.
(10, 2)
x = 12 y = 2 (12,2) satifies the equation
The ordered pair is (1, 3).
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
There are an infinite number of ordered pairs. (-5, -7) is one pair
(4.25, 0.25) is a solution.

There are infinitely many ordered pairs: each point on the straight line defined by the equation is an ordered pair that is a solution. One example is (0.5, 2.5)
There are an infinite number of ordered pairs that satisfy the equation.
(10, 2)
(0, 6.5) is one option.
The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the line and a solution to the equation.
Substitute the values of the ordered pair into the relation. If the equation is valid then the ordered pair is a solution, and if not then it is not.
y=(-1) x=(2)

Always. Every ordered pair is the solution to infinitely many equations.
