Question

What is the solution?1.) (1, -1) 2.) (1, 2)3.) 14.) -2

Answer 1

By definition, in a System of Linear equations you can get the following when you solve it:

1. If the lines are parallel then the System of equations has No solution.

2. If the line intersect each other, then the System of equations has One solution, which is the point of intersection.

3. If they are the same line, then the System of equations has Infinitely many solutions.

In this case, you can see in the graph that the lines intersect each other at the following point:

`(1,-1)`

That is the solution of the system of equations.

The answer is the First option.
