A parabola has a directrix of y=-3 and a focus of (0,5). Show that the point (12, 10) must lie on this parabola. I was thinking, to solve this would I need to use the distance formula? If I’m wrong please explain.

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !

Dbc if u do the math and stuff that what i got let me know if i was wrong

The american colonies would have been ruled by a king.
