plug the x coordinate in the x part of the equation and plug the y coordinate in the y's part of the equation and solve
I'm guessing that you're looking at an ordered pair AND a list of equations. Since I can't see either of them, my chances of matching them up are not looking too promising.

(0, 6.5) is one option.
There are infinitely many ordered pairs tat are solutions. They are all points on the line represented by 5x-6y = 13
Plug your ordered pair into both of your equations to see if you get they work.
Tell whether the ordered pair (5, -5) is a solution of the system
Always. Every ordered pair is the solution to infinitely many equations.
Given the ordered pair (3, y), what value of ywould make the ordered pair a solution of the equation 4x − 2y = 24?12

There are an infinite number of ordered pairs. (-5, -7) is one pair
plug the x coordinate in the x part of the equation and plug the y coordinate in the y's part of the equation and solve
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)
an ordered pair Coordinates.
an ordered pair that makes both equations true
No, this is not necessarily the case. A function can have an infinite range of solutions but not an infinite domain. This means that not every ordered pair would be a solution.
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.
