Each has a slope of negative 3 and a y -intercept of negative 6 , so the system has no solution.
B
Each has a slope of negative 3 and a y -intercept of negative 6 , so the system has infinitely many solutions.
C
Each has a slope of negative 3 , but one has a y -intercept of 2 and the other has a y -intercept of negative 6 . So, the system has no solution.
D
Each has a slope of negative 3 , but one has a y -intercept of 2 and the other has a y -intercept of negative 6 . So, the system has infinitely many solutions.
