hey

OpenStudy (anonymous):

Identify which table shows a direct variation. what does that mean make it more clear plz

OpenStudy (popstar30977):

well that is the question @SirJames

OpenStudy (popstar30977):

@perl

OpenStudy (michele_laino):

hint: we have a direct variation, when we can write: y=k*x

OpenStudy (michele_laino):

namely, the ratio: y/x, is constant for all pairs (x,y) in your tables

OpenStudy (michele_laino):

for example, using the data of the table 2, we have: 3/1.5=2 12/8=3/2=1.5 so 3/1.5 is not equal to 12/8

OpenStudy (popstar30977):

?????? >_< i have no clue because i am really not good at math

OpenStudy (popstar30977):

@Michele_Laino

OpenStudy (michele_laino):

using the data of your first table, we get: 7.5/3=...? 11.25/4.5=...? 17.5/7=...? please complete

OpenStudy (popstar30977):

why are they all 2.5

OpenStudy (popstar30977):

they are both the same right

OpenStudy (michele_laino):

yes! that is the meaning of direct variation

OpenStudy (michele_laino):

all three ratios are equal to 2.5
