This is a vertical line. Vertical lines are composed by points who share the same x coordinate.
That's why the equation of the line is exactly 
, where k is the shared x coordinate.
In your case, the common x coordinate is 3, so the line is 
Its 324 due to the fact that 18 would come out to be 9 so twice of 9 is 18 and 18 times by 18 equals 324
First, find the number in the 10 thousands place. In 1,346,935, 4 is in the 10 thousands place. 6 is next to 4, and is larger than 5, so round 40 thousand to 50 thousand. The answer is 1,350,000.
