Answer:
-9/2
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
-8-1/-3-(-5)
-9/2

Answer:
C. populations are non normal and the sample sizes are large.
Step-by-step explanation:
To test hypotheses about the difference between two populations means we deal with the following three cases.
1) both the populations are normal with known standard deviations.
2)both the populations are normal with unknown standard deviations.
3) both the populations are non normal in which case both the sample sizes are necessarily large.
So option C is the correct answer.
1st we should find the point where the line intersects with the axises
put x= 0 , so y= 3 ---- > the 1st point (0,3)
put y=0 , so x = 7.5 ----> the 2nd point (7.5,0)
so it's the first graph on the left
