hope the answer I provide will be help full
if these points are not forming an triangle therefore formula of colenearity has been used
there fore
A(1,3)
B(2,4)
C(3, P)
so formula =
x1(y2-y3) +x2 ( y3-y1) +x3 ( y1-y2) =0
putting up values
1( 4-P) + 2 ( P-3) + 3( 3-4)=0
4-P + 2P - 6 + 9- 12=0
P -5 =0
P=5
therefore value of is equal to 5.
