Answer:
y=6.5x
Step-by-step explanation:
Choose a point on the graph and tell what the point represents.
The point (2, 13) represents the height of the balloon after 2 seconds.
What is the constant of proportionality?
Because
height
time
=
13
2
= 6.5, the constant of proportionality is 6.5.
Write an equation in the form y = kx.
y = 6.5x
