Y=9x what is the answer

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 =

its c because i have that test too
