5.1 Linear Inequalities in Two Variables

Question 1

What are half-planes and how can they be divided?

Answer 1

A line divides the plane into two regions called half-planes. A vertical line
divides it into left and right half-planes; a nonvertical line divides it into upper and
lower half-planes. In either case, the dividing line is called the boundary line of
each half-plane
