Distance between two points P(x1, yi) and Qlx2, y2) in a straight line is iven by V(x2-x1)2 + (y2-y1)2 and the Slope of a straight line is given by:m (y2-y:) /(2-x), where Pll. yl and two points on the line. If the point Pixi, y1) on a straight line, which has slope m, then the equation of the sig Create a module called straight line to compute, the distance between two points in a straighnt ine slope of a straight line and the equation of a straight line Write a test program to test your module.
