Answer: The correct option is (C) 
Step-by-step explanation: Given that line k has a slope of
and line m is parallel to line k.
We are to find the slope of line m.
We know that
if two straight lines are parallel, then they have equal slopes.
Since line m is parallel to line k, so we must have
slope of line m = slope of line k.
Therefore, we get
Slope of line m is equal to 
Thus, (C) is the correct option.
