a. parallel to the line y = 5x + 13
b. perpendicular to the line y = 5x + 13

Which of the following​ equations, written in standard​ form, is parallel to the line y = 5x + 13 and contains the point (-5,2) ? Choose the correct answer below.


A. 5x + y = 27

B. x - y = -7/5

C. 5x - y = - 27

D. x + y = 7/5
Answer
Write an equation in standard form of the line that contains the point (1,-6) and is
a. parallel to the line 4x + 9y = 2
b. perpendicular to the line 4x + 9y = 2

Which of the following​ equations, written in standard​ form, is parallel to the line 4x + 9y = 2 and contains the point (1,-6) ? Choose the correct answer below.


a. 9x - 4y = 15

b. 9x - 4y = 50

c. 4x + 9y = -50

d. 4x + 9y = -15
Answer
b. Which of the following​ equations, written in standard​ form, is perpendicular to the line 4x + 9y = 2 and contains the point (1,-6) ? Choose the correct answer below.

9x - 4y = 58

9x - 4y= 33

4x + 9y = -33

4x + 9y = -58
Answer
9x - 4y = 58

9x - 4y= 33

4x + 9y = -33

4x + 9y = -58

(-9x + 4y = -33 wasn't a answer on this list)
Answer
Find the required linear model using​ least-squares regression.

The table below gives the total sales​ (in billions of​ dollars) for the aerospace industry.

Year 2006 | 2007 | 2008 | 2009 | 2010| 2011|

Total Sales 183.9 | 186.2|187.8|189.0 |190.0|190.8|

​(a) Find a linear model for the data with x = 6 corresponding to the year 2006.
​(b) Assuming the trend​ continues, estimate the total sales for the year 2015.

​(a) The linear model for the data is y = [ ] x + [ ]. (Round to two decimal places as​ needed.)
