so h = 7, k = -2, meaning the vertex is at (7, -2).
the squared variable is the "y", meaning is a horizontal parabola.
the "p" distance is negative, for a horizontal parabola that means, it's opening towards the left-hand-side.
we know the focus and directrix are "p" units away from the vertex, and we know the parabola is opening horizontally towards the left-hand-side.
the focus is towards it opens 1 unit away, at (6, -2).
the directrix is on the opposite direction, 1 unit away, at (8, -2), namely x = 8.
Basically, u just sub in any number for x and solve for y
y = -6x - 2.....lets say x = 0
y = 6(0) - 2
y = -2....so when x is 0, y is -2 .....(0,-2)
y = -6x - 2....lets say x = 1
y = -6(1) - 2
y = -6 - 2
y = -8.......another solution is (1,-8)
y = -6x - 2....lets say x = 2
y = -6(2) - 2
y = -12 - 2
y = -14....another solution is (2,-14)
y = -6x - 2....lets say x = 3
y = -6(3) - 2
y = -18 - 2
y = -20...another solution is (3,-20)
I think u get the idea now :)
