Answer:
[tex]\huge\colorbox{red}{B)a coordinate pair}[/tex]
Step-by-step explanation:
- the solution to a system of linear equations who has only one solution is always a coordinate pair
see an example in the graph:
a system of linear equation which has a solution:
[tex]\begin{cases}x+y=5\\x-y=3\end{cases}[/tex]
we can see the graph of the system of linear equation that it one solution is a coordinate pair (4,1)
