Answer:
A. negatively skewed
Step-by-step explanation:
Plot the values of salary against years
You will notice that;
- The graph has a long left tail
- The tail is longer towards the negative direction of the number line
This mean that this graph is a negative skewed graph/left-skewed distribution
In the <u>attached sketch of the plot</u>, join the points with a smooth curve and observe the above mentioned properties.
The x-axis scale ranges from 2000 to 2015 where 0=2000, 1=2001,2=2002......,15=2015
Hope this will give you a visual picture of the negatively- skewed distribution
Answer:
y2 = m(x2 - x1) + y1
Step-by-step explanation:
Given the slope formula :
m = (y2 - y1) / (x2 - x1)
To obtain an equivalent expression :
We cross multiply :
m(x2 - x1) = y2 - y1
Making y2 the subject ;
Add y1 to both sides
m(x2 - x1) + y1 = y2 - y1 + y1
m(x2 - x1) + y1 = y2
y2 = m(x2 - x1) + y1
