Answer:
C is the answer
Step-by-step explanation:
If you graph them on a line the outcome will be a straight line making it functional and a proportion
Y= -2x-5
Y=8x+5
^^ those two equations are basically the same so you put them side by side like:
-2x-5=8x+5
Subtract 5 on both sides which leads to:
-2x-10=8x
Add 2x both sides:
-10=10x
Divide both sides by 10
-1=x
The "system" of equations can't be solved for (x, y), because there's no "system" of equations given. There's really only one equation.
Either of these two equations can be massaged to look exactly like the other one. And if you graph both equations, you find that they're both the same line on the graph.
ANY point on the line is a solution to both equations ... and we all know how many different points there are on a line.
