Question

Point E is located at (–5, 2). Point M is the reflection of point E across the y-axis. What is the distance between E and M?

Answer 1

Answer:7

Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7
