Question

This table shows a proportional relationship between x and y.

x y
0 0
1 2
2 4
3 6

Find the constant of proportionality (r). Using the value for r, enter an equation in the form of y+rx.

Answer 1

The constant of proportionality is 2
2/1 =2, 4/2=2, 6/3=2

Equation: i learned it as y=2x but knowing the constant of proportionality you should be able to know what the equation is

Answer 2

Answer: The proportion is 2.

Explanation:

Go through the chart dividing y by x.

2 divided by 1 is 2

4 divided by 2 is 2

6 divided by 3 is 2

The constant is 2.
