Given,

The co-ordinates of two points P and Q are (2,6) and (−3,5) respectively.

Gradient of PQ=

y−6=1/5(x−2)

5y−30=x−2

5y=x+28

Let the line PQ intersect the x-axis at point A (x,0).

So, on putting y=0 in the line equation of PQ, we get

0=x+28

x=−28

Hence, the co-ordinates of the point where PQ intersects the x-axis are A(−28,0).
