<span>lie in the same plane. I'm pretty sure they are from what the sentence say so they all will Lie in the same plane. hope this helps</span>
<u>Given</u>:
The equation of the line passes through the point (1,1) and having a slope of 3.
We need to determine the equation of the line.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Substituting the point (1,1) and the slope m = 3 in the above formula, we get;

Simplifying the terms, we get;

Adding both sides of the equation by 1, we get;

Thus, the equation of the line is 
Hence, Option C is the correct answer.
1/3 x (3^-2 x 3^5)
1/3 x (1/3^2 x 243)
1/3 x (1/9 x 243)
1/3 x 27
