Answer:
No
Step-by-step explanation:
Y=1/2x-3
y=0.5x-3
y=6x
(6,0)
D - their slopes are negative reciprocals of each other.
Y=1/16x^2
multiplying both sides by 16 we get:
16y=x^2
The general form of a parabola is:
(x-h)^2=4p(y-k)
thus
4p=16
p=4
The parabola opens upwrd:
Focus: (h,k-p)
(0,0-4)
=(0,-4)
Directrix: y=-4
