Medals will be given, and a friend will be gained

Answer 1

y = 4x - 11
y = 4x + 11
y = 4x + 7
y = 4x - 7

These are the answer choices.

Answer 2

slope intercept form equation \[\huge\rm y =mx + b\]
m is slope
b is y-intercept
m=4
replace m by 4 and replace x and y by (-3,-1)

Answer 3

Okay.. give me a sec to write that.

Answer 4

in order pair first number is x and 2nd one is y \[\huge\rm (x ,y)\]

Answer 5

sure :)

Answer 6

Okay, (x,y) whats the next step?

Answer 7

replace x and y by their values and tthen solve for b

Answer 8

Okay so... just to double check:
y = mx + b
-3 = 4 -1 + b

Is this right?

Answer 9

@rvc can help

Answer 10

x = ??
y = ??

Answer 11

like i said
first number in order pair is x and 2nd one is y
like alphabetical order x ,y ,

Answer 12

x = -3
and y = -1

Answer 13

@Nnesha is perfect

Answer 14

yes right so replace x by -3 and y by -1

Answer 15

thanks rvc :)

Answer 16

@ribhu this area is for asking question don't post comments which is not related to this post
thanks use chat bars

Answer 17

Okay... -1y = 4 -3x + b I wasn't sure if the x and y needed to be in there, I just put them in there for you to see.

Answer 18

no u have to substitute so
\[\huge\rm -1 = 4(-3) +b\]
and u have to write -3 in parentheses

Answer 19

now multiply 4 times -3

Answer 20

Oh okay my bad. -12

Answer 21

\[\huge\rm -1 = -12 + b\]
solve for b by adding 12 both side

Answer 22

-1 = -12 + b
+12 +12

Correct?

Answer 23

nope both side mean left and right side of equal sign

Answer 24

-12 + -1 = -13
and than its... -12 + b, or -12 + -12?

Answer 25

I have not been good at this stuff since I started. Sorry.

Answer 26

u have to solve for b and at right side there is already NEGATIVE 12 so add 12 both side
