Perpendicular Lines and Distance p p The shortest distance between a line and a point not on the line is the length of the perpendicular line connecting them Equidistant: the same distance- parallel lines are equidistant because they never get any closer or farther apart The distance between two parallel lines is the distance between one line and any point on the other line In a plane, if two lines are equidistant from a third line, then the two lines are parallel to each other

Steps to find the distance between parallel lines: 1. 2. 3. 4. 5. Change the first equation so that the slope is now perpendicular to the given slope. (do not change anything else) Set the new equation equal to the second given equation Solve for x. Plug in for x in the new equation (the one with the perpendicular slope) and solve for y. Find the distance between the ordered pair created with x and y and the y-intercept from the changed equation (the one with perpendicular slope).
