The figure below shows a line graph and two shaded triangles that are similar: Which statement about the slope of the line is true?
A). It is throughout the line. 
B). It is −3 throughout the line. 
C). The slope from point O to point A is times the slope of the line from point A to point B. 
D). The slope from point O to point A is 3 times the slope of the line from point A to point B.
