The graph below shows the relationship between two variables.

Which scenario is BEST represented by the graph?

David drove at a constant speed before slowing down in a school zone. He then increased the speed of his car.

The number of perfect test scores by students in a math class increased from the first to the second grading period and then began to decline.

After a period of slow growth, the height of a plant remained the same for 2 weeks. It was then fertilized and began to rapidly increase in height.

The number of employees at a store increased at a constant rate for 5 years. There was a decrease in the number of employees for 2 years. Then the number of employees increased at a greater constant rate for the next few years.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
