All the coordinates have equal values for \(x\) and \(y\). This is shown by the points on the line such as (10, 10) and (-4, -4). Graph A is \(y = -x\). All the coordinates have \(x\) and \(y ...

Mathematicians have long sought to develop algorithms that can compare any two graphs. In practice, many algorithms always seem to work efficiently. But in theory, there is no guarantee.

Coordinates are given in the form (\(x\), \(y\)). The first number is the position in the \(x\)-direction (horizontal) and the second is the position in the \(y\)-direction (vertical).
