Answer 1

what are the options

Answer 2

y = –2x – 4
y = 2x + 4
y = –2x + 4
y = 2x – 4

Answer 3

y=-2x-4

Answer 4

thought so thanks

Answer 5

shld I explain

Answer 6

yes please because i guessed it was that answer.

Answer 7

the equation of a line is y=mx +b

Answer 8

You know that right?

Answer 9

yes

Answer 10

b=y intercept where the graph hits the y axis or another way to put it is the y value where x = 0

Answer 11

can u tell me what the y intercept is from looking at the graph?

Answer 12

-4?

Answer 13

ya

Answer 14

ok so how did you get the positive 4?

Answer 15

where did I get a +4?

Answer 16

oh wait my bad i thought you put y=-2x4 but you put y=-2x-4.

Answer 17

ok then I take any point on the graph so i took (-2,0) and plugged 0 into y and -2 into x and then you solve for a which is the slope

Answer 18

Did u follow?

Answer 19

a little i keep forgetting that y is vertical, and x is horizontal. But x comes first because it's b4 the alphabet.

Answer 20

Good way of remembering

Answer 21

But what did you get when you solved for a?

Answer 22

i don't follow you.
