Answer: y= 9x+1
Step-by-step explanation:
Even though I'm only in 7th grade....
Divide 19/2= 9. Something
19-1=18, and 18/2=9
Do the same to others to check
y = x^2 - 8x + 3
y - 3 = x^2 - 8x + 3 - 3
y - 3 = x^2 - 8x + ___
c = (8/2)^2 = 16
y - 3 + 16 = x^2 - 8x + 16
y + 13 = (x - 4)^2
y + 13 - 13 = (x - 4)^2 - 13
y = (x - 4)^2 - 13
Vertex: (4, -13)
Hope this helps!
The second or third one I believe
Either 4/30 or 2/15. they ate both the same thing but one is reduced
