** Ax + By + C = 0 ** or

Above is a program that will help you visualize how changing the values for the
variables ** A**,

Notice that the slope is equal to the opposite of ** A** divided by

**Summary of Details**

This linear function:

*f(x) = (-A/B)x + (-C/B) *

May be graphed on the x, y plane as this equation:

*y = (-A/B)x + (-C/B) *

This equation is often also written as:

*Ax + By + C = 0*

- This equation is called the general form for a line.
- The graph of this equation is a straight line.
- The slope of the line is
.*(-A/B)* - The y-intercept is
.*(-C/B)*
