Compare the function y= ¼ x  to  y = ¼ x +5 What is the difference between the two functions. 

• The y-intercept of y= ¼ x is 5 units higher than the y-intercept of y = ¼ x +5. 
• The y-intercept of y= ¼ x is 5 units lower than the y-intercept of y = ¼ x +5. 
• The graph of y= ¼ x is 4 times as steep than the graph of y = ¼ x +5. 
• The graph of y= ¼ x is a fourth  as steep than the graph of y = ¼ x +5. 

The parent function f(x) = x is graphed on the coordinate plane. The graph of the new line is formed by changing the slope of the original line to 4 and the y-intercept to 10. Which statement about the relationship between these two graphs is true? 

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

If the function is shifted 5 units to the left and goes down 2 units, which of the following would represent the transformation? 

• f(x +5) - 2
• f(x + 2) -5
• f(x-5) -2
• f(x -2) -5
