Dennis has a maximum of $80 that he can spend on books. He wants to buy a combination of nonfiction books which cost $12 each and fiction books which cost $8 each. To evaluate his decision, Dennis makes a graph with the number of nonfiction books bought on the x-axis and the number of fiction books
bought on the y-axis. He graphs a linear equation that models the fact that he has $80 to spend.
Which two ordered pairs represent points on the line that Dennis graphs?
(4,5)
(5,4)
(7.2)
(2,7)

( 2, 7 )

2 Nonfiction , 7 Fiction

Step-by-step explanation:

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
