What is the equation of the line expressed in slope-intercept form? A. y = –6x – 1 B. y = 6x + 1 C. y = x – 6 D. y = –x + 6 http://static.k12.com/calms_media/media/1534000_1534500/1534081/1/ebf2574ba686938564e3ee9216f835af756fd1ce/MS_IMC-140917-107043.jpg

Could you help me with a couple after this just check my answers?

Nnesha (nnesha):

what you got ??

OpenStudy (twizttiez):

What is the y-intercept of the line represented by the equation? y = 7x + 2 Answer 2 What is the slope of the line –6y + 2x = 18 in simplest form? Answer 1/3

OpenStudy (twizttiez):

What is the standard form of the equation? 3x = 2y – 4 A. 3x = 2y – 4 B. 3x – 2y = –4 C. 3x + 4 = 2y D. 3x – 2y + 4 = 0 Answer B

OpenStudy (twizttiez):

Am i right?

Nnesha (nnesha):

yes u are right but what's ur answer for first one ???

OpenStudy (twizttiez):

Idk

OpenStudy (twizttiez):

I'm lost on that one :| sorry

Nnesha (nnesha):

first you have to find y-intercept y-intercept is where line cross y-axis look at ur graph and see the point where line touch y-axis

OpenStudy (twizttiez):

So 6

OpenStudy (twizttiez):

Correction -6

Nnesha (nnesha):

yes -6

Nnesha (nnesha):

now you don't reallly have to find slope look at ur answer choices

OpenStudy (twizttiez):

Oh so C?

OpenStudy (twizttiez):

@Nnesha

Nnesha (nnesha):

yes and it can't be A or D bec line is increasing which mean slope should be positive

Nnesha (nnesha):

line increasing = always positive slope line decreasing = always negative slope

OpenStudy (twizttiez):

Thanks!

Nnesha (nnesha):

my pleasure :)
