The line of reflection is obviously a horizontal line. The only horizontal line in the answer list is ...
A. y = -2

Often, it's not about knowing how to work the problem. It's about being able to eliminate bogus answers and recognizing the form the answer must have.

_____
You can find points on the line of reflection by finding the midpoint between corresponding vertices. Those midpoints are (-4, -2), (-3, -2), and (-1, -2). The line through all three of those points is y = -2.

<h3>Solving equations.</h3>

From the information given, it was stated that Kim has 8 dollars less than twice Ricky. This will be:

= (2 × x) - 8.

= 2x - 8

Also, Ricky has x dollars. Therefore, the amount that they have together will be:

= 2x - 8 + x

= 3x - 8
