There is no such thing as "Straght" in math: the word does not [yet] exist in the English language. It is not easy to define "staright". You start off with a set of primitive mathematical concepts and then define other concepts using them. A straight line is a primitive geometric concept: it is the shortest distance between two distinct points in a plane. [You will probably need to use the concept of straight to define shortest!]
define a subset
They define irrational numbers
A cashier uses math to define the total value of the items you buy.
They define one plane. A line is defined by two points, and it takes three points to define a plane, so two points on the line, and one more point not on the line equals one plane.
The y axis is a vertical line on the Cartesian plane and a straight line equation is the point at which it intercepts the y axis.
The Vertical Line Test for Functions: If any vertical line intercepts a graph in more than one point, the graph does not define y as a function of x. By the definition of a function, for each value of x we can have at most one value for y.

The line and the point define a plane.
