Question

Which statement explains whether y = 4x + 8 is a linear function or a nonlinear function?

1. It is a linear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are on a straight line.

2. It is a nonlinear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are not on a straight line.

3. It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line.

4. It is a nonlinear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are not on a straight line.

Answer 1

The correct answer is 3.

Answer 2

3 (linear)

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 1

and the degree of variable x is 1
