The given lines are
2x – y = 0 ………………………… (1)
4x + 7y + 5 = 0 …………………… (2)
A (1, 2) is a point on line (1).
Let B be the point of intersection of lines (1) and (2).
On solving equations (1) and (2), we obtain X= -5/18 and Y= -5/9
∴Coordinates of point B are (-5/18 , -5/9)
By using distance formula, the distance between points A and B can be obtained as
