Answer:
(-1,3)
Step-by-step explanation:
Thus;
When (-1,3) is placed in the relation 3x + y =0,the answer will be zero.
<h3>Calculations</h3>
Let;
x= -1
y= 3
3(-1) + 3 =0
-3 + 3 = 0
Plug them in... -4=x -5=y
-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)
-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)
Therefore the ordered pair IS NOT the solution.
Hope this helps :)
