Answer:
The trend line for scatterplot A will have a negative slope, and the trend line for scatterplot B will have a positive slope.
Step-by-step explanation:
The data in scatterplot A has a general decreasing trend. This is because as x increases, the values of y tend to decrease. This means the trend line will have a negative slope.
The data in scatterplot B has a general increasing trend. This is because as x increases, the values of y tend to increase. This means the trend line will have a positive slope.
