A straight line is the shortest distance between any two points in geometry. It is a perfectly straight one-dimensional figure that extends infinitely in both directions without any curves or bends. In mathematics, a straight line is usually described using equations in coordinate geometry, such as the slope-intercept form: y=mx+by=mx+by=mx+b where mmm is the slope (steepness) of the line and bbb is the y-intercept (where the line crosses the y-axis). In simple terms, a straight line has no curves and maintains the same direction throughout.
