Question

why is this function linear? this is a linear function because the line is curved. this is a linear function because it is a straight line. this is a linear function because it is going up this is a linear function because it keeps going

Explanation:

To determine why the function is linear, we analyze the options:

• The yellow option is incorrect because a curved line is not linear.
• The purple option is correct because the definition of a linear function (in the context of graphs) is that its graph is a straight line.
• The orange option is incorrect as a function going up doesn't define linearity (e.g., exponential functions can also increase).
• The teal option is incorrect as "keeping going" is not a definition of linearity.

Answer:

B. This is a linear function because it is a straight line.
