Which equation has a constant of proportionality equal to 0.25? Choose 1
1. y=25x
2. y=5/2x
3. y=1/4x
4. y=1/25x

 The correct answer is:

___________

         →  3)  "   " .

___________

Step-by-step explanation:

___________

Let us consider all the answer choices given:

___________

1) " y = 25x " ;  

Note:  This equation has a constant of proportionality that is "25" ;  

and: "25 ≠ 0.25 " .

 Rule out "Choice 1 " .

___________

2) " y = " ;  

Note:  This equation has a constant of proportionality that is " " ;  

and:  " " = = 2.5 " ;  and:  " 2.5 ≠ 0.25 " .

Rule out "Choice 2 ".

___________

3) " y = " ;  

Note:  This equation has a constant of proportionality that is " " ;

and: " " = " (1 ÷ 4)" = " 0.25 " ;  and: " 0.25 = 0.25 " ; which suggests that this is the correct answer!

___________

Let us consider the last answer choice:

___________

4)  " y = " ;

Note:  This equation has a constant of proportionality that is " " ;

and:  " " = " (1 ÷ 25 ) "  = 0.04 ;  and:  " 0.04 ≠ 0.25 " .

___________

The correct answer is:

→   Answer choice:  3)   " y =  " .
