You didn't provide much context as to how this is supposed to be solved but here are a few possible solutions:
Solution 1 - Finding the X and Y intercepts
x-intercept: (0,0)
y-intercept: (0,0)
Solution 2 - Finding the Domain and Range
Domain: (- ∞ , ∞)
Range: (- ∞ , ∞)
Solution 3 - Finding the Slope and y-intercept
Slope: 9
y-intercept: (0,0)
Solution 4 - Solve for y
y = 9x
Solution 5 - Solve for x
x =
