Check if `(x,y)` satisfies the equation is about seeing if a given point `(x,y)` fits into a certain equation. We do this by putting the values of `x` and `y` into the equation and seeing if both sides match. If they do, the point works in the equation; if not, it doesn't. This helps us confirm solutions, draw graphs correctly, and understand how numbers relate in math problems.
