Question

If the points (1, 2) and (3,4) lie on
the same side of the straight line
3x - 5y + a = 0 then a lies in the set​

Answer 1

Step-by-step explanation:

We have given that point let A(1,2) and point B(3,4) and the equation is 3x-5y+a = 0 putting both values of A and B in LHS of equation, we get 3*1-5*2+a = 0 --------(1) a = 7 3*3-5*4+a = 0 ------------(2) a = 11 From both equation we get the values of a a =7 and a= 11
