Answer:
Option (B)
Step-by-step explanation:
Sue's weight at the start of the year = 82 kg
Sue weighed herself at the end of every year, so that the straight line on the graph shows the gradual reduction in the weight every month.
Slope of the line will describe the reduction in the weight per month.
Let the two points on the given line are (1, 80) and (11, 60).
Slope of the line will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{60-80}{11-1}[/tex]
= -2 kg per month
(Here minus sign denotes the reduction of weight per month)
Option (B) will be the answer.
