You have to use the formule: y2-y1/x2-x1
-2-(-2)/4-(-3)=0/7
You just Said it it's 0,6666666666...
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
Answer:
16 degrees
Step-by-step explanation:
62= 46+x
16=x
