How to solve this problem. I need the whole SOLUTION. THANKS

There are two possible

There are two possible extension points as shown. Use the following formulas to find these points:
$x = x_1 + r(x_2 - x_1)$

$y = y_1 + r(y_2 - y_1)$

Note:
(x1, y1) = (1, -3) and
(x2, y2) = (4, -6)

For extension point 1, use r = -1/6; and for extension point 2, use r = 6/7.
