State which one of the following is true: The straight lines y = 3x – 5 and 2y = 4x + 7 are (i) parallel ,(ii) perpendicular , (iii) neither parallel nor perpendicular.

Given straight lines: y = 3x – 5 and 2y = 4x + 7 ⇒ y = 2x + 7/2
And, their slopes are 3 and 2
The product of slopes is 3 x 2 = 6.
Hence, as the slopes of both the lines are neither equal nor their product is -1 the given pair of straight lines are neither parallel nor perpendicular.
