Which point on the number line shows the graph of -5/4?

Please see attached image.

Step-by-step explanation:

The best way to find the location of the number line for this point is to use ticks every 1/4 (instead of the standard one unit). See how the number line is subdivided marking ticks every 1/4 (one fourth) of the unit instead of a whole unit in the attached image. That way it is easy to move exactly 5 one fourths to the left of the origin (zero) and place a "dot" in that location (this process is marked with orange arrows in the attached image)

a.)the line for function b is steeper
