To accurately determine how the graph shows the change from Line W to Line X, we need to consider the slopes of both lines.
-
If Line W has a negative slope and Line X has a positive slope, then the correct response would be: "There is a slope change from negative to positive and by a factor of 3."
-
Conversely, if Line W has a positive slope and Line X has a negative slope, then the correct response would be: "There is a slope change from positive to negative and by a factor of 3."
-
If the slopes change from positive to negative without changing in magnitude, the correct response would be: "There is a slope change from positive to negative and no factor change."
-
Lastly, if the slope changed but it was unspecified or unclear, the response might be simply: "The slope is changed by a factor of 3."
Since I can't see the image, you'll need to assess the slopes of Lines W and X to select the correct response.
