A line is defined by the equation Y = 3x-6. The line passes through a point whose y-coordinate is 0. What is the x- coordinate of this point?

6 67

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
