(a.) y = 2x2 + 6
(b.) 2x – 2y = 2
(c.) y – 2 = 4 (x + 2)
(d.) y = 5

Answer: C (y – 2 = 4 (x + 2) does not represent a linear function
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is not 1 or 0.
