Answer: The line of reflection must be x=5.


Step-by-step explanation:

Given: In the diagram, polygon ABCD is flipped over a line of reflection to form a polygon with its vertices at A′, B′, C′, and D′. Points A′, B′, and D′ are shown, but the line of reflection and point C′ are not .

coordinates of C from the graph = (4,2)

If the coordinates of C'=(6,2)

we can see that value of y isn't change with reflection therefore the line of reflection would be x= ordinate of C'+ ordinate of C divided by 2=6+4 divided by 2=10 divided by 2=5

Therefore, the line of reflection must be x=5.

In order to find line of reflection, we can calculate mid-line of most touching coordinates which is C & C'

Here, C = (4, 2) & C' = (6, 2)

We can easily see, the reflection here is across y-axis on x-axis, 
so it would be: 4 + 6 / 2 = 10/2 = 5

In short, Your Answer would be: 5th line of x-axis

Hope this helps!

VashaNatasha [74]

Answer:

this question is not complete. need another equation

Step-by-step explanation:

give another equation then I can solve

\frac{3}{8} x =  \frac{17}{24}  -  \frac{1}{3} y \\ x =  \frac{17}{9}  -  \frac{8}{9} y
