The standard slope form of a line is another name for the standard form, Ax + By = C. Do not confuse it with the common slope-intercept form, y = mx + b, where m is slope and b is the y-intercept. All of the forms of a linear equation can be converted among each other using simple algebra. The easiest form to initially use depends on what information you are given.

The point-slope form of a linear equation for a line through points (x1, y1) and (x2, y2), where m is the slope is:
m = (y2 - y1)/(x2 - x1
The y-intercept form is y = mx + b, where b is the y-intercept.
The general form of a linear equation is Ax + By + C = 0
The standard slope form is Ax + By = C
Here is an example of how to derive the different forms:

The slope generally means how a line is inclined with x axis.The slope is given by the formulae a/b where a is the coeff of x and b is the coeff of y...for example take the line
y-3x+5=0.The slope is -(-3)/1 ie, 3..

Standard Slope form is y=mx+b
where m is the slope (rise over run) or (y2-y1)/(x2-x1).
and b is the y intercept (the point on the y (vertical) axis where the line crosses.
