problem

Points PP and RR are located at (1, 3) and (7, 15) respectively. Point MM is the midpoint of segment PRPR. Segment PRPR is reflected over the xx-axis. What is the sum of the coordinates of the image of point MM (the midpoint of the reflected segment)?
Plain-text mathematical notation (without MathML)
Points P and R are located at (1, 3) and (7, 15) respectively. Point M is the midpoint of segment PR. Segment PR is reflected over the x-axis. What is the sum of the coordinates of the image of point M (the midpoint of the reflected segment)?
Original LaTeX notation
Points $P$ and $R$ are located at (1, 3) and (7, 15) respectively. Point $M$ is the midpoint of segment $PR$. Segment $PR$ is reflected over the $x$-axis. What is the sum of the coordinates of the image of point $M$ (the midpoint of the reflected segment)?
