In the lesson on Linear Equations, our instructor begins with the definitions of linear equations and functions. She then dives into the standard form of equations as well as graphing with intercepts. The lesson is rounded out by four examples to test your knew knowledge.
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 numbers.
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.
