Identify the solution to the system of linear equations
Y=-x-2
Y=x-6

(-4, 2)

Step-by-step explanation:

By looking at the graph, the solution to the system of linear equations will always be where they intercept. If they both are the same line it means that there are infinite solutions, and if they don't intercept at all, that means there are no solutions.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
