A point P in a coordinate plane is labeled with a pair of ordered
numbers (a, b ) called coordinates:
a is the real number on the
x axis intersected by the line
perpendicular to the x axis
passing through P .
b is the real number on the
y axis intersected by the line
perpendicular to the y axis
passing through P .
a is called the x coordinate...
