Explanation
The correct answer is . It’s given that function is defined by . Therefore, the equation representing the graph of in the xy-plane is , and the graph is a line. For a linear equation in the form , represents the slope of the line. Since the value of in the equation is , the slope of the line defined by function is . It's given that line is parallel to the line defined by function . The slopes of parallel lines are equal. Therefore, the slope of line is also .
