In a question like this, you want to approach it with the equation "slope intercept form" which is

b = y-intercept
- the point where the line intercepts the y-axis
m = slope
I suggest using Desmos Graphing Calculator, it really helps and shows you a graphed equation. Let me know what you get!
9 = 1 + 8x - 8
Add 8 to both sides:
17 = 1 + 8x
Minus 1 on both sides:
16 = 8x
Divide both sides by 8
2 = x
Hope it helped :)
