imstuck · Answer

When you want to make the graph of a line steeper, the slope of the line has to be made greater.  The slope of your line y = 3x+1 has a slope of 3.  A from above has the same slope, so it's not A.  B has a negative slope, so it's not B.  C has a much less steep slope at 1/2, so that leaves D.  D is your answer and if you graph it you will see how much steeper that line is when compared to your original graph of y = 3x + 1.
