Answer:
1/4
Step-by-step explanation:
Answer:
The directrix is negative so the equation will be
x^2=4ay
x=-3
y=-5
a=x^2/4y
a=(-3)^2 /4*(-5)
a=9/20
x^2=4*(9/20)*y
x^2=9/5y
Step-by-step explanation:
The directrix always determine the equation to use. It is also important to notice the sign(-+).
y = 8-5x
Step-by-step explanation:
When two lines are parallel, it means their gradients are the same.
from the given equation
y = 9-5x
and comparing with the general equation of a line
y = mx+c, where m is the gradient, and c is the <em>y-intercept, </em>
m = -5
you can form a line parallel to that using the points (0,8)
(y-8)/(x-0)= -5
this would give you
y = 8-5x
