The lines are in the XYplane so you can write the two equations in the form y = mx + b and y = mx + c. Notice that the two lines have the same slope m they are parallel. The point (0, b) is on the first line and hence the line through this point with slope 1/m is perpendicular to the first line. Find the point (p, q) where this line intersects the second line and then find the distance between (0, b) and (p, q). Penny
