Question: the diagonals of a parallelogram pqrs are along the lines x+3y=4?
Answer: The Brainliest Answer! The slope of x +3y = 4 is 1/3 And 6x -2y = 7 is -3 So the product of the slope is 1/3 *(-3) = -1 Hence the diagonals are perpendicular to each other. Here the answer option can be rhombus as well as square.
