Slope

The measure of the tilt of a line, the rise over run or how much the line moves up for every movement to the right.

For a straight line in the plane, the slope is the tangent of the angle it forms with the positive X axis.

For a curve the slope is the slope of the tangent line.

If the slope is constant a line is straight.

A line joining two points

The slope is given by:

Where

m = slope
x1,y1 = cartesian coordinates of point 1
x2,y2 = cartesian coordinates of point 2
