Question

Choose the equation of the line passing through the point (-3, 1) and parallel to y = -x - 4.

A. y = x + 2
B. y = -x - 2
C. y = -x + 4
D. y = x - 4

Answer 1

help

Answer 2

@SolomonZelman @mohammad.arqum

Answer 3

y=-x+c
1=-x-3
x=-4

y=-x-4
i dont see this in the options
i cant be wrong now can I :O

Answer 4

So D ?

Answer 5

Okay, so when we are talking about a parallel line going through a certain point, we are not changing the slope only, we are only changing the y-intercept it is going through. (In other words, we are shifting the line vertically up or down).

I'll assume you know what parallel lines look like. And if you change the slope, you will change their slope, (or their incline) and this will make them intercept).

So, we will need to solve the equation for the y-intercept.
\(\large\color{black}{ y = -x + b. }\)
It has to be going through \(\large\color{black}{ (-3,1) }\),
So plug it ito the equation and solve for b.

Answer 6

@SolomonZelman man try to put the values into the equation im not getting a correct answer.!

Answer 7

So B or D

Answer 8

I think it's b

Answer 9

I'll plug it in for you, and you do it, @IndianBoyNiko okay?
\(\large\color{black}{ (1)=-(-3)+b}\)
can you solve for b?
I am sure B is correct though, but you seemed to just guess it...

Answer 10

I did the test before, i was just seeing if i got the answer right

Answer 11

B is right.

Answer 12

Ok thank you

Answer 13

can i ask another

Answer 14

OOOHHH silly mistake sorry about that....
y=-x+c
1=-(-3)+c
c=-2

y=-x-2
so its B

Answer 15

i'm just gonna ask it

Answer 19

holy cow thats alot of people lol

Answer 20

Oh sorry

Answer 21

Who cares. He obviously needs help!

Answer 22

use mathway.com

Answer 23

I just need two questions answered so i can see if i'm right

Answer 24

Don't mass tag

Answer 25

help ?

Answer 26

i think that answer is 'B' @IndianBoyNiko

Answer 27

For which question ? @shereenkhan

Answer 28

Which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x) - 3?
this question brother :)

Answer 29

you want ti tnaswered, or explained?
I'll do the second only:)

Answer 30

I'll give you a couple of examples of how graph is shifted for some different functions.

Answer 31

Here, you go,
`Example 1`.

Answer 32

Thank you.. but what about number 1

Answer 33

Here you go with another one,

Answer 34

which one? can you remind me please?

Answer 35

If f(x) is the total cost, in dollars, of x candies, which of the following statements best describes the meaning of f(2) = 6?

A. The total cost of 2 candies is $6.
B. The total cost of 6 candies is $2.
C. The total cost of 2 candies is $3.
D. The total cost of 3 candies is $2.

Answer 36

which one do you think? Do you have an opinion?

Hint: `f(2) = 6` means that, when you plug in 2 for x, you get 6.

Answer 37

The one i put was A
