solve the system of equations and choose the correct answer from the list of options.

2x + y = −4
y = 3x + 2

(-6/5, -8/5)
(-8/5, -6/5)
(-6/5, -11/5)
(-11/5, -6/5)

(-6/5, -8/5), you substitute 3x+2 for the y in the first equation. So the first equation will read 2x+3x+2, then you solve and get x= -6/5. Then you have to solve for y, so you put your x value (-6/5) in the second equation for x. it should read y= 3(-6/5)+2, the answer to that is y= -8/5. After that you just put them in order (x,y) and there's your answer. 

Aquadratic function is one of the form f(x)=ax2 + bx + c l, where a,b, and c are numbers with are not equal to zero.
