Answer:
B. {(0,2), (1,3), (4,3), (1,2)}
Step-by-step explanation:
A relation is not a function if the same input value maps to multiple output values. Essentially, if any x is repeated, it is not a function.
The second set, {(0,2), (1,3), (4,3), (1,2)}, has x-values of 0, 1, 4, 1, so 1 is repeated. It is not a function.
Assuming the equations are:
<span>−4x+y=−6
8x−2y=14
The second equation can be rewritten (divide by -2) to
-4x+y=-7
This system has no solutions. If you would draw them as lines, they are two parallel lines that never intersect.</span>
