It depends upon what you have been given.
One possibility is that you have a function, for example $y = 2 x + 3$ $y = 2x+3$ and want to establish the point on the coordinate grid for when $x = 5$ $x=5$
Substituting your value for $x$ $x$ into the function gives a value for $y$ $y$ (in the example $y = 13$ $y=13$ )
So you are looking for the point $(x, y) = (5, 13)$ $(x,y) = (5,13)$ (in this example)

This point is located $5$ $5$ units to the right of the coordinate origin and $13$ $13$ units up.
