Decide whether the statement is true or false. The slope of the graph of a linear function cannot be undefined Choose the correct answer below O A. The statement is false. If the slope of the graph is undefined, then the function can be written in the form f(x) = b. Such a function is linear O B. The statement is true. A vertical line is not a function and the slope of a vertical line is undefined O C. The statement is false. The slope of the graph of a line can always be found by evaluating f(0) O D. The statement is true. A horizontal line is not a function and the slope of a horizontal line is undefined. 88
