A linear function is a function of the form f(x) = ax + b, where a and b are real numbers. Here, a represents the gradient of the line, and b represents the y-axis intercept (which is sometimes called the vertical intercept).
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form.
The standard form or the general form of linear equations in one variable is written as, Ax + B = 0; where A and B are real numbers, and x is the single variable. The standard form of linear equations in two variables is expressed as, Ax + By = C; where A, B and C are any real numbers, and x and y are the variables.
To find the slope using a general or standard form equation, use the slope formula: m=-A/B where A and B are integer variables found in the equation. The m is the slope.
A General Form does not have any specific requirements and can be used for just about anything. This type of Form does not record data for specific users.
How to Find the Equation of a Line from Two Points Find the slope using the slope formula. Use the slope and one of the points to solve for the y-intercept (b). Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
The general form of the equation of a line ? ? + ? ? + ? = 0 is closely related to its standard form: ? ? + ? ? = ? , where ? , ? , and ? are integers and ? is nonnegative. We can convert the standard form into general form by subtracting the constant ? from both sides of the equation.

General Form: ax + by = c To graph equations of this form, such as 3x − 2y = −6, find the x- and y-intercepts (Method 2), or solve the equation for y to write it in the form y = mx + b and construct a table of values (see Example 2).
