If you meant, your two equations are y=2x+2 and y= 8x+1
your vertex will be at x=1/6 and y=7/3
you can plug these in and they will check out.
but if you meant, y=(2x2) +8x+1
y=4+8x+1
y=8x+5 and then you only have one line so there will be no vertex. but the y intercept is at (0, 5) and your x-intercept at (-5/8, 0)
if neither are these are what you are saying, sorry, and maybe try and repost and I will help you out.
