What is the Equation of a Line?

A line is defined as the one-dimensional figure that has no thickness. It extends infinitely in both directions. In the coordinate system, a straight line is described using the standard equation. The standard form is known as the equation of a line. If the slope and the intercept values are given, the equation of a line can be found easily. So, it is also known as the slope and intercept form.

Standard Form

The standard form to represent the equation of a line is as follows:

Equation of a Line, y = mx + b

Where

“m” is the slope of the line

“b” is the y-intercept

Frequently Asked Questions on Equation of a Line Calculator

How to find the slope of a line?

The slope of the line defines the direction of the line. Thus, to find the slope of a line, divide the difference of y coordinate points by the difference of x coordinate points. Thus, the formula to find the slope of a line is given as:

Slope, m = [y2 – y1]/[x2 – x1] = Rise/Run

What are the different forms of a linear equation?

The three different forms of linear equations are:

  • Standard Form: Ax + By= C
  • Slope Intercept Form: y= mx + b
  • Point Slope Form: y -y1 = m (x – x1)

What is the equation of the horizontal line?

We know that the slope-intercept form of a line is y = mx+b. For the horizontal line, the slope value is zero (i.e., m=0). Thus, the equation becomes y = b. Here, b is the y-intercept
