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 )
Point A is on the coordinate 4 and point B is on the coordinate -1. If we want to find the distance between two points in a coordinate plane we use a different formula that is based on the Pythagorean Theorem were (x 1 ,y 1) and (x 2 ,y 2) are the coordinates and d marks the distance:ethod 2: If we are working in a coordinate plane where the endpoints has the coordinates (x 1 ,y 1) and (x 2 ,y 2) then the midpoint coordinates is found by using the following formula: Video lesson: Find the midpoint of the line segment. 1  Pre-Algebra. 2  Algebra 1.
