Select the correct answer from each drop-down menu. Which system of linear equations makes the sentence true?
(-2x + y = 7, 3y = 6x + 4),(-2x = -11 - y, 2y = 4x + 3),(2x + y = 4, 5y = 10x + 4),(2x + y = -7, -6y = 12x + 42)is a system of linear equations representing intersecting lines.
(-2x + y = 5, 5y = 7x + 4),(2x = -1 - y, 2y = 6x + 5),(-4x + 2y = -9, 2y = 5x + 3),(2x + 3y = 21, -6y = 4x + 1)is a system of linear equations representing parallel lines.
(-2x + y = 3, 5y = 10x - 15),(-2x + 4y = 9, 8y = 4x + 18),(-x + 2y = 4, 6y = 3x + 11),(-7x + 3y = 1, -12y = 28x - 4)is a system of linear equations representing coincidental lines.
