The fourth figure represents a linear function because your graph is a line.
For solving this question you should identify which graphs represent a linear function.
A linear function can be represented by a line. The standard form for this equation is:
[tex]y=ax+b=0[/tex], for example [tex]y=2x+7[/tex].
Your exercise shows 4 figures:
- Figure 1 - It is not a line. The graph is a parabola, therefore it does not represent a linear function.
- Figure 2 - It is not a line. The graph is a polynomial function, therefore it does not represent a linear function.
- Figure 3 - It is not a line. The graph is a hyperbole, therefore it does not represent a linear function.
- Figure 4 - It is a line. The graph is a line, therefore it represents a linear function.
Hence, you must select the fourth figure.
