A tangent line is a line that is parallel to and intersecting a point on a curve, where the limit of the distance between two points on that curve (one of them being the point in question) and those two points also being on that line approaches zero. Since a straight line has only one slope, at all points on the line, then there can only be one tangent line to a straight line, and the tangent line is the same line as the straight line.
Yes. If it is not straight, then it is not a line.
it just a straight line
If it is not straight, then it is not a line.
The word straight does have an antonym, which is crooked. So perhaps a crooked line is the opposite of a straight line.
