Question

How do I reflect it ?

Answer 1

The letters will be the same distance from the y-axis
You jus flip it over the y axis and count the distance of the letters

Answer 2

For the new reflected image, the coordinates will be:
M': (8, 2)
A': (7, 6)
T': (2, 6)
H': (3, 2)
Plot the points, connect them, label them, and you'll have your reflected image.
Hope this helps! :)
