Question

-1
1
5

Answer 1

Now if this shifts five to the right, what will your k value become?

Answer 2

-2 -> 5 right

Answer 3

-5

Answer 4

Sec

Answer 5

-1

Answer 6

No, wait I think your answer should be y = 2x-6

Answer 7

But I don't see that option in your solutions mhm

Answer 8

No that's not it

Answer 9

it's a +6, the integer is positive because they already told you that function is y = 2x-k so it's a positive integer not negative

Answer 10

I guess, go with +5

Answer 11

Idk though because if you graph it out you should get y=2x-6

Answer 12

thanks

Answer 13

Unless I'm wrong or thinking about something else haha, let me tag someone to verify I suppose @ganeshie8 hey could you check this out haha?

Answer 14

y=2(x-5) +4
= 2x - 10 + 4
= 2x - 6

k = 6

Answer 15

thats not an option

Answer 16

I thought so, so the solutions they gave you are wrong, you should ask/ tell your teacher.

Answer 17
