20/t=v and 12/t=(v-4)  solve both for t

t=20/v  and t=12/(v-4)  since t=t

20/v=12/(v-4)  cross multiplying...

20v-80=12v

What other point will appear on the line representing this proportional relationship where the constant of proportionality is 2?
Bumek [7]

Answer:

B

The equation of proportionality is

y = kx ← k is the constant of proportionality

Here k = 2 , then

y = 2x

This means that the y- coordinate is twice the x- coordinate

The only point where this is true is the point

(2, 4 ) → B
