Question

Which equation below is not an equation that represents the graph shown below
y + 2 = -3(x - 1)
3x + y =1
y - 1 = -3(x + 2)
y = -3x + 1

Answer 1

i have A

Answer 2

why?
what is the slope of the line shown?

Answer 3

Answer B and D are the same!

Answer 4

@Courage. slope of line shown?

Answer 5

and y intercept?

Answer 6

ok lets see

Answer 7

A,B,and C are the same @gregbrutsche1

Answer 8

so there is one equation that is not represented on the graph

Answer 9

yes, its the only one that does not have a slop of -3 and a y intercept of 1
three of the equations are y=-3x+1 when you simplify.

Answer 10

slope*

Answer 11

ABD SAME

Answer 12

uhohhh we got us a fancy display pic

Answer 13

woops I meant D not C

Answer 14

ok

Answer 15

courage first tell us what the y intercept is
and slope of this line is

Answer 16

remember slope =rise/run
and y intercept is where it hits the y axis line

Answer 17

y + 2 = -3(x - 1) \(\implies y=-3x +1\)
3x + y =1 \(\implies y= -3x+1\)
y - 1 = -3(x + 2) \(\implies y=-3x-4\)
y = -3x + 1

Answer 18

the y intercept is 1 and the slope intercept is 3/-1

Answer 19

those are actually iff statements:P

Answer 20

NO i just meant that thats what the equation turns into

Answer 21

noob!

Answer 22

maybe i jut like the arrow! >:( lol.

Answer 23

im playing

Answer 24

so is @Jhannybean correct

Answer 25

I jjust translated your options into slope-intercept form.you figure it out.

Answer 26

Dan hush......lol.

Answer 27

a teacher once told me the most under/best used symbol is

I use it so much now.

Answer 28

@Courage look at your y-intercept first. does it match any of your answer choices?

Answer 29

yea

Answer 30

and you would not HAVE to use iff its still a correct statement, but leaves out information
(a iff b) implies (a implies b)
but not vice versa:)

Answer 31

which one? @Courage.

Answer 32

d

Answer 33

lol @dan815

Answer 34

Omgoodnesss. You guys are SO CRITICAL lol.

Answer 35

its not us, its the maths:)

Answer 36

Good job @courage

Answer 37

math is a very cynical language

Answer 38

ok
