The linear graph of these would be B.
Why: The definition of a linear function is "Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y," and as you can see, the only one that is a straight line that goes across the graph would be B.
