Line equation and slope form

Let us study about Slope Intercept Form,

A line equation makes the straight line when it is graphed. If the line passes through the points A (x1, y1) and B (x2, y2) and then its slope is,

Slope (m) = (y2 - y1) / (x2 - x1)

The slope is defined as the relation between the perpendicular distance and flat distance between any two points. The slope is denoted by letter ‘m’. The slope is also called as the gradient.

I hope the above explanation was useful.
