In mathematics, a straight line is the simplest geometric
object. It's a one-dimensional figure that extends infinitely in both
directions. You can think of it as a perfectly straight path between two
points.
In the Cartesian coordinate system, a straight line can be
represented by the equation \(y = mx + b\), where \(m\) is the slope of the
line (which determines its steepness or incline) and \(b\) is the y-intercept
(where the line crosses the y-axis).
Alternatively, a straight line can also be represented by
the equation \(Ax + By + C = 0\), where \(A\), \(B\), and \(C\) are constants,
and \(A\) and \(B\) are not both zero.
No matter how it's represented, a straight line has the property that any two points on the line can be connected by a line segment that lies entirely on the line.
