M is the midpoint of Point A (0, 0) and Point B (6, - 10). What is the x-coordinate of M?

PLEAS HELPPP

The function is  .this means that if a point (a,b) is on the graph of the function, then:                                     .thus, we check that: .this means that (1, -1), (-1, -1), and (-3,-17) are on the graph.answer: (1, -1), (-1, -1), and (-3,-17)
