Gradient and Intercepts
In mathematics, the term gradient or slope is often used to describe how steeply a straight line lies. Given two points
and
to form a line
, we define the gradient of the line
as the ratio
going from one point to another along line
.

Let
be the gradient of line
, then
m=increase in yincrease in 1
