In this lecture you will learn about Linear Equations and Functions. You begin with understanding the Standard Form as well as Graphing with Intercepts. This Algebra lesson ends with a series of four complete video examples.
A linear equation
can be written in the form ax + by = c, where a, b, and c are real
numbers. This is called the standard form of the equation.
A linear function
can be written in the form f(x) = mx + b where m and b are real
The graph of a
linear equation or linear function is a straight line.
The x coordinate
of the point at which the graph crosses the x axis is called the
x-intercept. The y-intercept is defined similarly.
