Read the following SAT test question and then click on a button to select your answer. 

If the graph of the function f is a line with slope 2, which of the following could be the equation of f?

Answer Choices

Answer

The graphs of all the given functions are lines, and the equations are all in the form  y = (m times x) + b. When a linear equation is in the form  y = (m times x) + b, the slope of the graph of the equation is m , the coefficient of x. The graph of the function f is a line with slope 2, so the only choice that could be the equation of f is function f of x = (2 times x) + 4.
