A question to do with graphical solutions of equations.

[From: ] [author: ] [Date: 11-10-14] [Hit: ]
...how?! Thanks!......
Assuming the graph of y=x²-8x-7 has been drawn, find the equation of the line which should be drawn to solve the equation 2x²=16x+2

I tried so many times but i keep getting it wrong! The answer is y= -2.5....how?! Thanks! Oh and pls don't use complex methods such as equations coz i haven't done that yet... i'm in year 11 (15 years old)

Hello,

You have drawn the graph defined by
y = x² - 8x - 7

= = = = = = = = = = = =
