Question

Please help! This is the third time I asked

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:

Answer 1

Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx

Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5

Then plug K value into equation
Y=6.5X

Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.

Check:
X=50

Y=6.5x50
Y=320
