Answers are in the attachment, #4 and #5
#4) the line would fit the data better if it had a smaller positive slope
#5) The line is not a good fit because it is not close to all the data points
Explanation.
#4)
the red line that was given has a slope of 3/1 and it is a very sloped line. The green line I drew goes through more of the data points and it’s slope is 3/4, a smaller more gradual slope. This confirms answer #4.
#5)
The red line does NOT go through many data points. The green line I drew goes through many more points so it is a good fit. So the red line is not a good fit proving answer #5.
