infinite solution
Step-by-step explanation:
hello
we substitute b = 4a + 2 in the second expression

<=> -6 = -6
which is always true
so there is infinite solution
hope this helps
Hello,
If center is (0,0)
x²/a²+y²/b²=1 for a half horizontal axis of a, and a half vertical axis of b
Here
a=2 ==> a²=4
b=8 ==> b²=64
![\boxed{\dfrac{x^2}{4}+ \dfrac{y^2}{64}=1}\\](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cdfrac%7Bx%5E2%7D%7B4%7D%2B%20%5Cdfrac%7By%5E2%7D%7B64%7D%3D1%7D%5C%5C)
