Ok, so from previous question
(x-h)^2=4p(y-k)
distance from focus to directix is 2
2/2=1=p
1>-1
focus is above the vertex
1 unit down from (0,1) is (0,0)
vertex at (0,0)
since focus is above, p is positive
(x-0)^2=4(1)(y-0)
x^2=4y
4y=x^2
divide both sides by 4
y=(1/4)x^2
f(x)=1/4x^2
2nd one is answer
-4x -6 = -5y + 2
5y = 4x + 6 + 2
5y = 4x + 8
Y = g(x) = 4/5x + 8/5
Answer:
Integers: a number that can be written without a fractional component
Rational Numbers: is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number
Step-by-step explanation:
How are points graphed
on a coordinate plane?
Start at (0, 0), or the origin.
Move over x units to the right or left.
Move over y units up or down.
Mark the point.
