If a trend line has equation y = -2x + 5, what type of association would you expect the data to have?
To determine the type of association you would expect from the given trend line equation, you need to examine the slope (-2) and the y-intercept (5).
The slope of -2 indicates a negative association. This means that as the x-values increase, the y-values will decrease. In other words, there is an inverse relationship between x and y.
Additionally, the y-intercept of 5 suggests that when x is equal to 0, the corresponding y-value is 5.
Therefore, based on the equation y = -2x + 5, you would expect the data to have a negative association (inverse relationship) between x and y, where y decreases as x increases, and the line intersects the y-axis at the point (0, 5).
