Question

find the distance between pq.​

Answer 1

Answer:

To find PQ, we'll extend PQ, meeting the Y-axis at R. Now, PQ can be expressed as QR – PR. Since PR is parallel to the X-axis, it will be perpendicular to the Y-axis. Therefore, PR is the perpendicular distance of P from the Y-axis, which is equal to the x-coordinate of P, i.e. x1.
