Answer:
Step-by-step explanation:
Use the slope-intercept formula:
m is the slope and b is the y-intercept. Use the slope formula first:
Rise over run is the change in the y-axis over the change in the x-axis. Plug in the coordinates:
Simplify parentheses (two negatives makes a positive):
Simplify:
The slope is 
. Insert into the equation:
Now, to find the y-intercept, take one of the points and substitute for the x and y values of the equation:
Solve for b, the y-intercept. Simplify parentheses:
Add 
to both sides:
Simplify:
The y-intercept is 
. Insert this into the equation:
Finito.

Answer:
-23
Step-by-step explanation:
As I increases by 18, y decreases by 12. From the last value in the table, I needs to increase by 2·18 for it to become zero. Hence the y-intercept will be 2·12 less than the last value in the table:
1 - 2·12 = -23 . . . the y-intercept
Answer: F. Statistic, because the data set of salaries of 50 employees is a sample.
Step-by-step explanation:
A parameter gives measure of a characteristic for the entire population where as a statistic gives measure of a characteristic for the subset of population (sample).
Given : The average annual salary of 50 of a company's 800 employees is $54,000.
It means the sample size = 50 and the sample mean salary= $54,000.
i.e $54,000 is giving the measure for mean salary for the sampled 50 employees.
It means $54,000 is a statistic .
Hence, the correct answer is option (F).
10% of 50kg is 5kg
50kg add 5kg is 55kg
=55kg
