PLEASE HELP PLEASE HELP

the solution to a system of linear equations who has only one solution is always
A- a fraction
B- a coordinate pair
C- a negative number
D-a decimal

Answer 1

`\huge\colorbox{red}{B)a coordinate pair}`

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:

`\begin{cases}x+y=5\\x-y=3\end{cases}`

we can see the graph of the system of linear equation that it one solution is a coordinate pair (4,1)

Answer 2

The point where the two lines intersect is the only solution. An inconsistent system has no solution.
