Which equation represents a linear function?

Answer:
D)y=1/4x
Step-by-step explanation:
Its the only answer that is a straight line
Answer:
(D) y = 1/4x
Step-by-step explanation:
(A) is incorrect because that is an absolute value function. This causes the graph to look like a sharp "v".
(B) is incorrect because that is an exponential function. This is because the "x" is raised to the second power. The graph would resemble a "u".
(C) is incorrect because that is an exponential function. This is because the "x" is raised to the third power. The graph would resemble a "u".
(D) is correct because the "x" is only raised to the first power. The base equation for a linear function is y = mx + b. The graph would resemble a straight line.
