Answer:
B. The system may have infinitely many solutions
D. The system may have no solution
Explanation:
we know that
If a system of linear equations contains two equations with the same slope
then
we may have two cases
case 1) The two equations are identical, in this case we are going to have infinite solutions
case 2) The two equations have the same slope but different y-intercept, (parallel lines) in that case the system has no solution.
