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:

10 Units

Step-by-step explanation:

Since point E is located at E (-5,2)

And point M is the reflection of point E  across the y-axis.

∴ M (5,2)

Now we have to find the distance between the points E and M.

$D = \sqrt({x2-x1)^{2} + (y2-y1)^{2}  }$

$D = \sqrt({5-(-5))^{2} + (2-2)^{2}  }$

$D = \sqrt({10)^{2} + (0)^{2}  }$

$\sqrt{100}$

∴ D = 10 units

∴ The distance between the two points is 10 units
