Corbettmaths Equation of a Line Answers 2025: Ultimate Guide
Understanding the Equation of a Line
The equation of a line is a mathematical expression that describes the relationship between the points on the line. It can be used to find the slope, y-intercept, and other properties of the line.
Slope-Intercept Form
The most common form of the equation of a line is the slope-intercept form:
y = mx + c
where:
-
yis the dependent variable (the value that changes) -
xis the independent variable (the value that stays the same) -
mis the slope of the line -
cis the y-intercept of the line
Point-Slope Form
Another common form of the equation of a line is the point-slope form:
y - y₁ = m(x - x₁)
where:
-
(x₁, y₁)is a point on the line -
mis the slope of the line
Finding the Equation of a Line
There are several methods for finding the equation of a line, including:
- Using the slope and y-intercept
- Using two points on the line
- Using a point and the slope
