Write an equation in the form of y=kx for the graph below. (k=y/x) K is in decimal
Form

k = 3.5

Step-by-step explanation:

From the graph in the picture attached,

Relation between balloons height (y) is directly proportional to the time (x)

y ∝ x

y = kx

Where 'k' is a proportionality constant.

Now we substitute the point (8, 28) in the equation,

28 = k(8)

k =

k = 3.5

k ≈ 3.5

Therefore, value of constant 'k' is 3.5

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
