Question

The graph below shows four straight lines, A, B, C, and D:

graph of line A going through ordered pairs negative 2, negative 3 and 2, 5.Graph of line B going through ordered pairs negative 2, negative 4 and 2, 4. Graph of line C going through ordered pairs negative 2, negative 5 and 3, 5. Graph of line D going through ordered pairs 0, negative 4 and 4, 4

Which line is represented by the function f(x) = 2x + 1?

Line A
Line B
Line C
Line D

Answer 1

Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.

y - 1 = 4(x - 3)
y + 1 = 4(x + 3)
y - 3 = 4(x + 1)
y + 3 = 4(x - 1)

Answer 2

hi

Answer 3

you are correct

Answer 4

The graph of a function f(x) is shown below:

Answer for Blank 1:

Answer 6

g(x)=2x+2
k=2

Answer 7

so k is 2? @AlexandervonHumboldt2

Answer 8

yeah

Answer 9

Jason has already read 27 pages of a book. He plans to read 3 pages of the book every day. If f(n) represents the total number of pages that Jason will complete reading in n days, which of the following functions represents the relationship between f(n) and n?

f(n) = 27n - 3
f(n) = 3n - 27
f(n) = 27n + 3
f(n) = 3n + 27

Answer 10

correct

Answer 16

@AlexandervonHumboldt2

Answer 17

y = negative two thirdsx + 6

Answer 18

The table below shows the distance d(t) in feet that an object travels in t seconds:


t
(second)
d(t)
(feet)
3
126
4
224
5
350
6
504


What is the average rate of change of d(t) between 3 seconds and 5 seconds, and what does it represent?
59.5 m/s; it represents the average speed of the object between 3 seconds and 5 seconds
112 m/s; it represents the average speed of the object between 3 seconds and 5 seconds
112 m/s; it represents the average distance traveled by the object between 3 seconds and 5 seconds
59.5 m/s; it represents the average distance traveled by the object between 3 seconds and 5 seconds

Answer 19

t d(t)
3 126
4 224
5 350
6 504
