The point ( t , 2 t ) lies on the line 4 x ? 3 y + 6 = 0 . Find the value of t .

1. The point ( t , 2 t ) lies on the line 4 x ? 3 y + 6 = 0 . Find the value of t. Substitute the coordinates of ( t , 2 t ) in for x and y :. 4 x ? 3 y + 6 = 0. 4( t ) ? 3(2 t ) + 6 = 0. 4 t ? 6 t + 6 = 0. ?2 t + 6 = 0. 6 = 2 t. = t. 3 = t. 2.
