Answer:
1st option
Step-by-step explanation:
The equation for the 2nd option will be y = 1/x which is a hyperbola
The equation for the 3rd option is I'm unsure because it is not linear as it does not have the same jump between the y values
The equation for the 4th option is not linear as it does not have the same jump between the y values
Hope this helped and have a good day
Combine like terms
X^9 = -3
divide both sides by 9
-3/9 or -1/3 reduced
