Y= x + 6
y = x^2

solve the system using substitution

a) (-3, 9), (2,4)
b) (-5, 25), (1,1)
c) (3, 9), (-2, 3)
d) (5, 25), (-1, 1)

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.
