Slope =change of y / change of x = (0-4)/(0-1) = -4/ -1 = 4
Equation of a line : y=mx+b where m is the slope, 4 and b is the y intercept, 0 (from the second point given.
Y=4x
The directrix is x=-2, which means the parabola opens horizontally instead of vertically. The equation is (y - k)²<span> = 4p (x - h), where the </span>focus<span> is (h + p, k) and the </span>directrix<span> is x = h - p
in this case, h+p=2, k=0, and h-p=-2
solve for h and p: h=0, p=2
plug the numbers into the equation: (y-0)</span>²=4*2(x-0)
simplify: y²=8x
