Which of the following equations are linear functions? Explain how you got your answer.
Select the three linear functions.
A. y = x to the power of 2 – 1
B. y = 2x + 1
C. y = 1/2x – 5
D. y = 1/3x to the power of 2
E. y = -x


  1. Answer:
    B, C, and E
    The reason B, C, and E are the answer’s is because the equation of a linear equation is y= mx+b. B, C, and E are written this way. We can eliminate A and D because They are quadratic equations, because the X is squared.
