Which ordered pair would form a proportional relationship with the point graphed below?

Hey there! I'm happy o help!

To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.

-10(-1/3)=3 1/3≠30

30(-1/3)=-10≠-15

-30(-1/3)=10

80(-1/3)=-26 2/3≠-30

Therefore, the correct answer is (-30,10).

Have a wonderful day! :D

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
