The equation for this is ; y=1/2(x+4)^2-1
Explain
we use the vertex form
y=a(x-h)^2+k where the vertex is (h,k)
Select ( -4,-1)
Where h=-4
K=-1
y=a(x-h)^2+k
We get
y=a(x-(-4))^2+ -1
Y= a(x+4)^2+-1
Now replace to 0,7
7=a(0+4)^2-1
7=a(4)^2-1
7=16a-1
So now
7=16a-1
7+1=16a
8=16a
a=8/16
That should 1/2
So y=a(x+4)^2 -1
Should become
Y=1/2(x+4)^2 -1
Do you have any doubts now !
The answer is 22 because you multiple 8 by 2 3/4
Answer:
y = 1/2x + 4
Step-by-step explanation:
Lines that are parallel have the same gradient....in which its 1/2
Equation of the line that is parallel to y = 1/2x + 5 and passes through (-4,2)
(y - 2) = 1/2(x + 4)
2(y - 2) = x + 4
; 2y - 4 = x + 4
Equation of the line,
y = 1/2x + 4
Answer:
