Answer: True False
Question 5
Marks: 1
The slope of a curved line differs from that of a straight line in that
Choose one answer.
a. straight lines are more realistic, but curved lines are not descriptively accurate for the real world.
b. 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.
