A non vertical line divides the plane into
Correct answer: B. upper and lower half planes
- A. left and right half planes
- B. upper and lower half planes
- C. four planes
- D. None
Explanation
When a nonvertical line divides the plane, it separates the plane into two distinct regions or half planes. However, the distinction between left and right half planes occurs when dealing with vertical lines. In the case of a nonvertical line, it divides the plane into upper and lower half planes. One side of the line is considered the upper half plane, and the other side is considered the lower half plane.

About Linear Equations
Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
