Question

Which of the following is a linear function?

y = x^3 + 1
five over six x = y − 4
y = 8x^2
y = one over five x

Answer 1

Which of the following is a linear function?

1. y = x^3 + 1
2. (5/6)x = y − 4
3. y = 8x^2
4. y =(1/5)x

2. (5/6)x = y − 4 and 4. y =(1/5)x are the right answers.

Explanation:

Linear function is in the form y=ax+b.
