The coordinates of point p on a coordinate grid are (−5, −6). point p is reflected across the y-axis to obtain point q and across the x-axis to obtain point r. what are the coordinates of points q and r? a. q(5, 6) and r(−5, −6) b. q(−5, −6) and r(5, 6) c. q(−5, 6) and r(5, −6) d. q(5, −6) and r(−5, 6)
