Point A is located at (5,4)

To reflect over the y axis, we flip the sign of the x coordinate while keeping the y coordinate the same. The rule is $(x,y) \to (-x,y)$

So we will have $(5,4) \to (-5,4)$ as the location of A'

Unit rate = 3/8 : 1/6

We can also write this as:

3/8 / 1/6

Flip the 2nd fraction and multiply:

3/8 * 6/1

Multiply the numerators and denominators together:

18/8

Simplify by dividing the numerator and denominaotr by 2:

18 / 2 = 9
8 / 2 = 4

So we have:

9/4
