Find the constant of proportionality k. Then write an equation for the relationship between x and y.

X | 2 | 4 | 6 | 8 |



Y | 10 | 20 | 30 | 40 | I tried to make the table

k = _, y =

see explanation

Step-by-step explanation:

Given x and y are in proportion then the equation relating them is

y = kx ← k is the constant of proportion

To find k use an ordered pair from the table

Using (2, 10 ), then

10 = 2k ( divide both sides by 2 )

5 = k , thus

y = 5x ← relationship between x and y

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest
