properties of the simplest geometric figure – straight line. Despite its simplicity, the line is a vital concept of geometry and enters into our daily experiences in numerous interesting and useful ways. Main focus is on representing the line algebraically, for which slope is most essential. 9.2 Slope of a Line
A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point. A straight line does not have any curve in it. It can be horizontal, vertical, or slanted. If we draw an angle between any two points on the straight line, we will always get a 180-degree.

What Is a Straight Line? A line is a geometry object characterised under zero width object that extends on both sides. A straight line is just a line with no curves. So, a line that extends to both sides to infinity and has no curves is called a straight line. Download this lesson as PDF:-Straight Lines PDF. Equation of a Straight Line
The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept. It is the most common form of the equation of a straight line that is used in geometry.
Let’s understand the basics and equations of straight lines and how to calculate the distances from a point. Basics of Straight Lines. Various Forms of Equation of Line. Distance of Point from a Line. FAQs on Straight Lines.
A straight line is the simplest figure in geometry but it forms the most important concept of it. Where do you find straight lines? A straight road; edge of the ruler, building, pen, pencil; hands of clocks etc. are few examples of it. Let us discuss other features of a line and the basics of straight lines.
Equation of a Straight Line. The equation of a straight line is usually written this way: y = mx + b. (or "y = mx + c" in the UK see below) What does it stand for? y = how far up. x = how far along. m = Slope or Gradient (how steep the line is) b = value of y when x=0. How do we find "m" and "b"?
In geometry, a straight line, usually abbreviated line, is an infinitely long object with no width, depth, or curvature, an idealization of such physical objects as a straightedge, a taut string, or a ray of light.
