WebSolution. Step 1: Extend a perpendicular line segment from A A to the reflection line and measure it. Since the reflection line is perfectly horizontal, a line perpendicular to it would be perfectly vertical. Step 2: Extend the line segment in the same direction and by the same measure. Answer: A' A′ is at (-6,1) (−6,1). Webx = 2 y + 1 y − 3 x (y − 3) = 2 y + 1 x y − 3 x = 2 y + 1. Obtain all terms with the variable y on one side of the equation and everything else on the other. This will enable us to treat y as a GCF. x y − 3 x = 2 y + 1 x y − 2 y = 3 x + 1 y (x − 2) = 3 x + 1 y = 3 x + 1 x − 2. Answer: f − 1 (x) = 3 x + 1 x − 2. The check is ...
