The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
2 answers:
Answer: If you plot a point in the y-axis at -6, you can plot two more points by using the slope "rise over run" Then draw a line connecting the points.
The coordinate of the y intercept is (0.-6) To find the first x values of the first 2 coordinates, add 1 then 2 to 0. To find the y values, add 2 then 4 to the -6
Step-by-step explanation:
From -6 go up 2 over 1 and plot at (1, -4 ) then up 2 over 1 again to (2, -2)
The x- intercept will be at (3,0)

Answer:
A.
B. 42.2 million
Step-by-step explanation:
Part A:
Given:
Newspapers circulated in year 2004,
Newspapers circulated in year 2014,
Let the time start at the year 2004. So,
For the year 2014,
Therefore, linear relationship between newspapers circulated and time passed since 2004 is given as:
Therefore, the equation describing the relationship is:
Part B:
For the year 2018,
Plug in 14 for in the above equation and solve for
. This gives,
Therefore, in the year 2018, the newspaper circulation will be 42.2 million.
