Homework Statement
Let f be a function from R2 to R. Suppose that f (x, y) → 3 as (x, y) approaches (0,1) along every line of the form y = kx + 1. What can you say about the limit lim(x,y)→(0,1) f (x, y)? Check the box next to the correct statement.

The Attempt at a Solution
*The answer to the problem is "We cannot determine if the limit exists, but if t does, the limit is 3." But I really have no idea why, or what I should attempt to solve this. I'd appreciate any help on this, thank you!
