Which equation is represented by the table?

OpenStudy (clobber02):

OpenStudy (clobber02):

A. y = 5x – 1 B. y = –3x + 3 C. y = 3x + 3 D. y = 3x – 4

Nnesha (nnesha):

:-) this question is same like last one use same formula and find slope

Nnesha (nnesha):

all answer choices have different y-intercept so you can use this information y-intercept where x = 0

OpenStudy (clobber02):

ok

Nnesha (nnesha):

so when x = 0 y = what ??

OpenStudy (clobber02):

3????

Nnesha (nnesha):

there is not any "3" number in the table

OpenStudy (clobber02):

i dont know than

Nnesha (nnesha):

in order pair first value is x and 2nd one is y \[\huge\rm (x , y)\] so when x = 0 what y value is there

OpenStudy (clobber02):

0

OpenStudy (clobber02):

?

Nnesha (nnesha):

yes x =0 but what y = ??

Nnesha (nnesha):

x= 0 so when they replaced x by 0 in order pair you get\[\huge\rm (0 , y)\] so look at the table when first number is 0 of order pair what y value is there

OpenStudy (clobber02):

i really don't know

OpenStudy (clobber02):

i dont know...1?

Nnesha (nnesha):

not positive one

OpenStudy (clobber02):

-1

OpenStudy (clobber02):

oooohhhh so it goes down

OpenStudy (clobber02):

ooohhhh i get it

Nnesha (nnesha):

|dw:1425964644373:dw| when x is zero y is negative one
