Question

How many solutions does the system of equations below have?
y = –7x − 9
y = 23x − 89

Answer 1

Answer: infinitely many solutions

Step-by-step explanation: A system of two equations can be classified as follows:

If the slopes are the same but the y-intercepts are different, the system has no solution.

If the slopes are different, the system has one solution.

If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
