43 and 5/6 because 12 and 1/4*2 is 24 and 1/2 then 9 and 2/3*2 is 19 and 1/3 and when you add that you get 43 and 5/6
We get an infinite number of solutions when we have equivalent equations, for example equations that a scalar multiples of each other. That's not going to happen for two equations in slope intercept form unless all the terms are the same. None of those on this list.
So we're left with the second choice, and clearly the second equation is three times the first, with the same solution set, all the points along the line.
Answer: Second choice y=-3x + 4 and 3y = -9x + 12

Step-by-step explanation:
Note on how to solve such equation:
This is a quadradic equation. The figure shown is a parabola. This parabola opens downward. Now, this information is not necessary important for this particular situation; however, it needs to be retained for said class or for the near future.
The equation for a quadradic function is: f(x)=x^2+2
when x=-2, y=1
