Determine If The Tables And Graphs Below Express Direct Variation Between The Variables If Theydo Find The Constant Of Variation And An Equation That Defines T class=

Sagot :

7) Direct Variation between the variables

y = { 5, 10, 15, 20, 25 }

x = { 1, 2, 3, 4, 5 }

Constant of Variation: 5

Equation: y=kx

8) Not Direct Variation

y = { 1,2,4,8,12 }

x = { 1,2,3,4, 5 }

y=kx

(1)=k(1) , k=1

(2)=k(2) , k=1

(4)=k(3) , k=4/3

(8)=k(4) , k=2

(12)=k(5) , k=12/5
