Find k, the constant of proportionality, for the data in this table. then write an equation for the relationship.

they equation needs to be in the form y=kx

k=

equation:

,  

,

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Find the value of the constant of proportionality k

take any ordered pair from the data

For x=25, y=160

substitute the values of x and y

simplify

The linear equation is equal to

or

answer: 5
