The question of distance between two straight lines arises only when they are parallel. The given lines are parallel. If the equations of parallel lines are ax + by + c = 0 and ax + by + c' = 0, then the perpendicular distance between them is given by. p = l c - c' l / sqrt ( a^2 + b^2 )
The distance formula is used to find the distance between two points in the coordinate plane. We'll explain this using an example below. We want to calculate the distance between the two points (-2, 1) and (4, 3). We could see the line drawn between these two points is the hypotenuse of a right triangle.he point that is at the same distance from two points A (x 1, y 1) and B (x 2, y 2) on a line is called the midpoint. You calculate the midpoint using the midpoint formula. We can use the example above to illustrate this.
