In the x–y plane, what is the y–intercept of the line l?

(1) The slope of the line l is 3 times its y-intercept.

(2) The x–intercept of line l is –1/3

As the OA is not given, I have arrived at answer C i.e both statements together are sufficient to answer the question. Please see below what makes me say this. Please let me know whether I am right or wrong.

Equation of line y = mx+c ------------------------------(1). Question is asking to find C.

Considering Statement 1 ----> m = 3c. So putting this value of m in (1) above we get y = c(3x+1). Not sufficient.

Considering Statement 2 ---> x intercept is -1/3 i.e. y = -m/3+c. -------------------------------(2)

Can't solve for C. Therefore insufficient.

Combining the statement 1 & 2 and substituting the value of m = 3c from statement 1 into statement 2. y = -3c/3+c => c-c = 0 Therefore, y = 0. Therefore C is the right answer.
