if i is a variable
if i is the imaginary unit defined by i²=-1
If y equaled 3, then we would plug 3 into the y spot on the equation. Therefore it would be 2x+4(3)=8. Now just solve.
2x+4(3)=8
2x+12=8
2x-12=8-12
2x=-4
2x/2=-4/2
X=-2
Hope this helped!

So we see our equation, clear:
y=8^x
Let's just plug in values of x from 1-4.
y= 8^1=8; So, it would be (1,8).
y= 8^2=64; So, it would be (2, 64).
y = 8^3= 512; So, it would be (3,512).
y= 8^4 = 4096; So, it would be (4, 4096).
Answer:
along the x it moved 3 and along the y it went 4
