|Ax + By = C|
where A , B , and C are integers, is the x-intercept, and is the y-intercept.
|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.
|y - k = m(x - h)|
where m is the slope of the line and ( h, k ) is some point on the line.
