Dr. Eaton continues this new section with Linear Functions. You will begin with learning the definition of Standard Form as well as multiple examples. Next, you will learn about graphs of linear functions and their x and y intercepts. Finally, you will cover graphing linear equations and what exactly are linear functions.
function is a function of the form f(x) = ax + b, where a and b are
constants and a is nonzero. Its graph 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. Values of x for which f(x) = 0 are called zeros
equation can be written in the form ax + by = c for some
constants a, b, and c, where either a or b is not 0. If these
constants are integers, the equation is in standard form.
The graph of a
linear equation is a straight line.
