Zina solves a system of linear equations by elimination and finds a solution of (2, 2). one of the equations is a + b = 4. what is the other equation?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
