The graph of y=kx is the graph of y=x scaled by a factor of |k|. the right of the y-axis, which would be at positive 8, and And then if I reflected that And draw a triangle. (P) = P. Reflecting over the x-axis: (the x-axis as the line of reflection) When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite. When you reflect a point across the line y = -x, the x-coordinate and the y-coordinate change places and are negated (the signs are changed). Lets graph this now. There are three basic ways a graph can be reflected on the coordinate plane. 88. example. She has a Ph.D. in Applied Mathematics from the University of Wisconsin-Milwaukee, an M.S. This confirms that the result of reflecting $\Delta ABC$ over the line of reflection $y = x$ is triangle $\Delta A^{\prime}B^{\prime}C^{\prime}$ with the following vertices: $A^{\prime} =(1, 1)$, $B^{\prime} = (-2, 1)$, and $C^{\prime} = (-2, 4)$. reflection across the y-axis.
