• The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up.

• The graph of the new line is steeper than the graph of the original line, and the y-intercept has been translated up.

• The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated down.
