Question

What is the standard form equation of the line shown below?

Answer 1

whats the equation

Answer 2

what do you think

Answer 3

y + 3 = −2(x − 1)
y = −2x − 1
2x + y = −1
−2x − y = 1

Answer 4

and i think it would be y=-2x-1

Answer 5

well what are the two coordinates first of

Answer 6

(1,-3) and (-2,3)

Answer 7

what kind of line is it positive or negative

Answer 8

negitive cuz its goin down

Answer 9

@johnweldon1993 wats ur opinoun as well

Answer 10

ok, so it would be going -2,3 and 1,-3 not the other way that would put you going backwards with everything ok

Answer 11

okay

Answer 12

Standard form is Ax + By = C

A,B,C are integers

for example, 7x + 10y = 3 is in standard form because A = 7, B = 10, C = 3

Answer 13

okayy

Answer 14

Something like y = -2x + 1 is in slope intercept form and NOT standard form.

slope intercept form is y = mx+b

Answer 15

rightt

Answer 16

So hopefully you see how B is not the answer they want. They want something in standard form.

Answer 17

yaa

Answer 18

Be extra careful with all of the instructions.

Answer 19

so it would be 2x + y = -1

Answer 20

plug in each point to confirm

Answer 21

do i plug in the points on the graph to the equation ? im confused

Answer 22

the point on the left is (-2,3)

so x = -2 and y = 3 here

plug x = -2 and y = 3 into 2x + y = -1 to get


2x + y = -1

2(-2) + 3 = -1

-4 + 3 = -1

-1 = -1


so the point (-2,3) is definitely on the line 2x + y = -1. Do you see how to check the other point?

Answer 23

yes to confirm your possible answer

Answer 24

yes i do thank you n sorry was wrighting it down

Answer 25

that's ok

Answer 26

il tag u if anymore

Answer 27

what do you mean?

Answer 28

like @jim_thompson5910 lol

Answer 29

oh gotcha

Answer 30

lol
