Question 46
LociFind the locus of points equidistant from two straight lines y − 5 = 0 and y − 3 = 0.
- A.y − 2 = 0
- B.y − 4 = 0
- C.x − 1 = 0
- D.y − 3 = 0
Show the answer and explanation
Answer: B (y − 4 = 0)
Explanation
The lines y = 5 and y = 3 are parallel; points halfway between them lie on y = 4, i.e. y − 4 = 0.
