Question

How do you solve this equation and what is the answer?

Answer 1

4th choice

Explanation:

If a line completely overlaps the other line, they are the same line with infinite solutions.

Answer 2

There are certain cases that need to be taken into consideration: 1. If the lines intersect at one point the solution that fits all equations is exactly that point. 2. If the lines do not intersect at only one point the system has no solution because the lines 3. If the system of equations intersects completely overlaps the other line we say that we have an infinite number of solutions that fits the equations.
