Question

Abed says he has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is y = 3x – 1. Which could be the other equation?

Answer 1

The correct answer is:

Any equation that is a multiple of y=3x-1.

Step-by-step explanation:

In order to graph as the same line, the equations must be the same. This means that all pieces of the first equation must be multiplied by the same factor, or the equation must be rewritten.

Answer 2

y = 3x + 23x – y = 23x – y = 1 3x + y = 1
