Y=3/8x describes a proportional relationship between x and y. What is the constant of proportionality?
1 answer:
Answer:
The constant of proportionality k is 3/8
Step-by-step explanation:
We are given which describes a proportional relationship between x and y. We need to define constant of proportionality
If y ∝ x then
y=kx where k is constant of proportionality.
Comparing the given with y=kx, we can find value of k i.e constant of proportionality.
So, k= 3/8
Hence, The constant of proportionality k is 3/8

Answer:
- check below for explanation.
explanation:
➢ Given coordinates:
- A( 1, 3 )
- B( 1, 6 )
- C( 4, 6 )
- D( 5, 2 )
➢ after a dilation with a scale factor of 1/2:
- A( 1, 3 ) ÷ 2 ☛ A'(0.5,1.5)
- B(1, 6 ) ÷ 2 ☛ B'(0.5, 3)
- C( 4, 6) ÷ 2 ☛ C'( 2, 3 )
- D( 5, 2) ÷ 2 ☛ D'( 2.5, 1)
➢ Plot the after dilation coordinates on the graph:
