Step-by-step explanation:
The directrix is a vertical line, so the parabola is horizontal. The focus lies to the left of the directrix, so the parabola opens to the left.
For a left-opening parabola:
x = a(y-k)²+h,
a < 0,
vertex (h,k)
focal length p = 1/|4a|
focus (h-p, k)
directrix: x=h+p
Apply your data
focus (1,-4)
directrix x=2
vertex (1.5,-4).
focal length p = 0.5
a = -1/|4p| = -½
x = -½(y-2)²+ ½

John is not correct
Step-by-step explanation:
<em>(Unless you meant 5:6)</em>
Make the base question into 
simplify as much as possible. I found the Greatest Common Denominator (GCF) of<em> 35</em> and <em>42</em>, which was<em> 7</em>
divide <em>35</em> and <em>42</em> by the GCF<em> (7)</em>, and you should get 5:6 as your answer.
