Question
The co-ordinates of two points P and Q are (2, 6) and (−3, 5) respectively Find the co-ordinates of the point where PQ intersects the x-axis.
Solution
Let the line PQ intersects the x-axis at point A (x, 0).
Putting y = 0 in the equation of the line PQ, we get,
0 = x + 28
x = −28
Thus, the co-ordinates of the point where PQ intersects the x-axis are A (−28, 0).
