The graph of the inequality x+2>0 is.
Correct answer: A. open right half plane
- A. open right half plane
- B. closed right half plane
- C. open left half plane
- D. closed left half
Explanation
The inequality \(x + 2 > 0\) represents all points \(x\) that are greater than 2. Graphically, this represents a halfplane to the right of the vertical line \(x = 2\), excluding the line itself because the inequality is strict (\(>\)). Since the line \(x = 2\) is not included, the half plane is open on that side.

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.
