Which of the following will be the solution for a two-order inequality?
2 answers:
In solving a two-order linear inequality, say
and 
We graph the corresponding linear equations;
Each of the two equations divides the cartesian plane into half-planes.
By testing for points, we identify the half-plane that satisfies each inequality.
The intersection of the two half-planes gives us a set of points that satisfies the two inequalities simultaneously.
Therefore the solution to the two-order inequality is the intersection of two half-planes.
The correct answer is option C

Explanation:
If both lines are parallel, then their slopes must be equal.
For the line PQ, the slope is:
Slope of PQ = </span> --- (1)
For the line P'Q', the slope is:
Slope of P'Q' =
Slope of P'Q' = --- (2)
As (1) = (2), hence the lines are parallel and their slope is (Option A).
