Question

If someone could check my answer, I'd appreciate it. If it's wrong, can you explain it to me? Thanks!

What are the equations of the lines of symmetry shown below?
[IMG]http://i57.tinypic.com/zn6iw0.gif[/IMG]

A. x=2 and y=5
B. x=3.5 and y=6
C. x=2 and y=3.5 <--- My answer!
D. x=3.5 and y=2

Answer 1

the question reads a little odd to me, but assuming they simply want a few of the equations of the sides of the rectangle ....

y = 3.5 doesnt seem to correspond for me

Answer 2

we pass thru x=2 and x=5; and y=6 and y=-2

Answer 3

as is, i cant say that i understand what they are asking for given those answer choices

Answer 4

The want to know the equations, for the lines of symmetry it has. So. Like the rectangle has 2 lines of symmetry, what are the equations of those two lines? :)

Answer 5

a rectangle has 2 lines of symmetry; the 'middle' lines

so we may want the midpoints for the xs and ys

what is the midpoint of 2 and 5?

what is the midpoint of -2 and 6?

Answer 6

3.5 and -4?

Answer 7

it looks like your original response found 2 and 3.5 but you attributed them to the wrong parts :)

x=3.5 and y=2 are more better

Answer 8

no - 3.5

Answer 9

Ohhh..

Answer 10

x=(2+5)/2 = 7/2 = 3.5

y=(6+-2)/2 = 4/2 = 2

Answer 11

Well that makes more sense..

Answer 12

:) good luck
