Relationship B has a greater rate than Relationship A. The graph represents Relationship A. Which equations could represent Relationship B? Choose all answers that are correct.

OpenStudy (anonymous):

OpenStudy (anonymous):

A: y=1/2x B:y=2.2x C:y=1.4x D:y=3x

@amistre64

or @gorv

OpenStudy (gorv):

u need to find the slope

OpenStudy (anonymous):

How do i do that?

OpenStudy (gorv):

slope = rate of change

OpenStudy (gorv):

u have 2 points

OpenStudy (gorv):

(x1,y1)=(2,4) (x2,y2)=(4,8)

OpenStudy (gorv):

slope = \[\frac{ y2-y1 }{ x2-x1 }\]

OpenStudy (anonymous):

those are the points?

OpenStudy (gorv):

yeah given in the Q

OpenStudy (gorv):

(1,2) it means x=1 and y=2

OpenStudy (anonymous):

so it's A?

OpenStudy (anonymous):

It's more than one answer choice by the way

OpenStudy (gorv):

what u got for slope ??

OpenStudy (anonymous):

i got a x

OpenStudy (gorv):

@Soniatonia

OpenStudy (anonymous):

@gorv

OpenStudy (gorv):

we will get slope of A=2 y=2x

OpenStudy (gorv):

so B must have slope >2

OpenStudy (gorv):

only fist has slope less than A

OpenStudy (gorv):

so remaining three is our ans
