Expert Answer:

Say the line equation is


All teh three point muat satisfy the equation

A(8,1) ==>   1=8m+c==>  8m+c-1=0---------(1)

, B(3,-4), ==> -4=3m+c==> 3m+c+4=0------(2)

Eqn 1-2======>  5m-5=0==> m=1

Put m in eqn 1  ==>c=-7

So the equation of the line is y=x-7

C (2, K )  ==>  K=2-7=-5
