Question 1042148
Lets think about a line x = 3 which is a vertical line parallel to y axis. This link passes through many points such as (3,-1), (3,-2), (3,0), (3,1), (3,2),(3,3),(3,4), (3,4.6) and many other points that their x=3 and their y can be any number.

The point (-1,3) is to the left of this vertical line. The distance between this line and (-1,3) is 4. If we draw the shortest line from the point (-1,3) to the line x=3, it will intersect the line at the point (3,3). 

The answer to this problem is the line x = 3
