Slope-Intercept Form

General Linear Form  -  Equations in general linear form look like this:

Ax + By = C    


where A , B , and C are integers, is the x-intercept, and is the y-intercept.
Slope-Intercept Form  -  Equations in slope-intercept form look like this:

y = mx + b    

where m is the slope of the line and b is the y-intercept of the line, or the y- coordinate of the point at which the line crosses the y-axis.
Point-Slope Form  -  Equations in point-slope form look like this:

y - k = m(x - h)    

where m is the slope of the line and ( h, k ) is some point on the line.
