ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions.

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12
