Reflection over the y-axis is like a mirror image across the vertical axis. It is equidistant from the y axis on the other side and the x coordinate stays the same.
So, your new point is the fourth choice, (4, -2).
First distribute in the 2 on the left side to get 6d+6=7+6d
Then, you would combine the variables to be on one side of the equation by doing -6d. However, this would cancel out the d by leaving you with 0d+6=7. That is the same thing as saying 6=7.
The answer to this equation is no solution because 6 is NOT equal to 7.
10/25 = 2/5 Because you divide both sides by 5
