How to do it Simply!!!!!!!!!!!!!!!!!
If the slope m of a line and a point (x1,y1) on the line are both known, then the equation of the line can be found using the point-slope formula: The slope of the line defined by the linear equation.
Definition of Distance Formula. The distance formula is used to determine the distance, d, between two points. If the coordinates of the two points are (x1, y1) and (x2, y2), the distance equals the square root of x2 − x1 squared + y2 − y1squared.
