Can someone me with this problem, . the problem is attached.

y = 3 is the line of reflection

Under a reflection in a line, corresponding points of the original and it's image should be equidistant from the line of reflection

y = 3 is the horizontal line passing through all the points with a y-coordinate of 3

A is 1 unit above and A' is 1 unit below the line

B is 3 units above and B' is 3 units below

C is 1 unit below and C' is 1 unit above

D is 1 unit below and D' is 1 unit above

The vertices of the figure and the image are all equidistant from y = 3

10% of increase is the final answer! : )

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
