a) Not enough information provided.
b) Need the data points to calculate the slope.
c) Slope = (change in y) / (change in x)
d) Slope is equal to the y-intercept.

Answer 1

The slope of a trend line can be calculated as (change in y) / (change in x). Data points are required to calculate the slope.

Step-by-step explanation:

The slope of a trend line can be calculated using the formula: Slope = (change in y) / (change in x). In order to calculate the slope, you need the data points of the trend line. Therefore, the correct answer is: b) Need the data points to calculate the slope.
