This graph shows a proportional relationship.

what is the constant of proportionality?

what is the answer as a ratio in simplified form in the box.

k=

5:4 or 1:0.8

Step-by-step explanation:

Since the graph ascends, it means when y(on the horizontal axis) increases, x (in the vertical axis increases)

This is an example of a direct proportion.

y=kx where k is the constant of proportionality.

From the point ( given,

Using the (x,y) coordinate notation,

Substituting into y=kx

Next we solve for k by multiplying both sides by

Our answer as ratio in simplified form is given as 5:4 or 1:0.8

add the table and i will answer correctly

step-by-step explanation:

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
