Answer:
Given, Point P(7,7),Q(3,4),R(h,k) are collinear
∴
3−7
4−7
=
h−3
k−4
=
4
3
=
h−3
k−4
...(I)
It gives, k=
4
3h+7
Also, (h−7)
2
+(k−7)
2
=100 ...(II) ∵PR=10
Now, by substituting the value of k in equation 2 and we got the resultant quadratic equation as follows:
h
2
−14h−15=0
Now by solving the above quadratic equation we got,
∴h=15 or h=−1
k=13 or k=1
∴ The point R can be (15,13) & (−1,1)
