Answer:
C
Step-by-step explanation:
the slope of a line is anyways the factor of x.
the slope of a perpendicular line is just the upside-down fraction of the original line slope, and its sign is flipped.
3x - 5y = 20
5y = 3x - 20
y = (3/5 × x) - 4
3/5 turns into -5/3
and the point coordinates must satisfy the line equation :
4 = (-5/3 × -6) - 6
4 = 30/3 - 6 = 10 - 6 = 4
correct.
so, C is the correct solution.
