B)the numerical value of the slope of a straight line is always higher than the numerical value of the slope of a curved line.
C)the numerical value of the slope of a curved line is different at every point but is the same at every point for a straight line.
D)the numerical value of the slope of a curved line is an irrational number, but the numerical value of the slope of a straight line is always a rational number.
E)straight lines are more realistic, but curved lines are not descriptively accurate for the real world.
