Question

If A point K is the reflection of L (2,5) IN THE Y AXIS WHAT IS THE LENGTH OF KL

Answer 1

How far is (2,5) from the y-axis?
K is the same distance away on the other side.

Answer 2

IT DOESNT SAY STEVE

Answer 3

Oh, my. I'm not asking you what it said; I'm asking whether you cannot figure out how far away from the y-axis the point (2,5) is.

draw the x- and y- axes, and plot the point (2,5). If you can do that, you can just look at the graph paper and see how far the point is from the y-axis.

Or, if you just want the algebra, then consider that reflection in the y-axis takes

(x,y) -> (-x,y)

so, K is (-2,5)

Now just drag out your good old distance formula and crank out the answer.
