Find the equation of the tangent to the curve y= x^3 - x^2 - x + 6 at the point where x= 3.
Give your answer in the form y = mx + c

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.
