ordinate is 3/2 times abscissa So, y=3x/2 Or, 2x+15x/2=19 Or, 19x=38 Or, x=2 => y=3*2/2 =3 The point is (2,3)

Ordinate means y-coordinate. It means we need to find a point on the given line where y-coordinte = 3/2 (x-coordinate) . Just put y = [ (3/2) * x ] in the given eqn. => 2 x + 5 (3/2) x = 19 => 2 x + 15 x / 2 = 19 => (4 x + 15 x) divided by 2 = [ 19 ] => x = 2 Hence the point is ......... ( 2,3 ) ..................
