Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
-8m + 6 - 2m = 9(3m + 4) +5m
-10m + 6 = 9(3m + 4) + 5m
-10m + 6 = 27m + 36 + 5m
-10m + 6 = 32m + 36
6 = 42m + 36
-30 = 42m
-5/7 = m
m = -5/7
