Help! 20 points, I can’t figure it out and my daughter is in 7th grade. The hard middle school years aha

(0, 0), (1, 4), (2, 8); 4

(0,0), (3, 1), (6, 2); 1/3

(0,0), (4, 2), (8, 4); 0.5

Step-by-step explanation:

3.

Part a:

Choose any 3 values for x. Plug them into the equation and find the corresponding y values.

y = 4x

Let x = 0:

y = 4x = 4(0) = 0

First point: (0, 0)

Let x = 1:

y = 4x = 4(1) = 4

Second point: (1, 4)

Let x = 2:

y = 4x = 4(2) = 8

Third point: (2, 8)

Answer to part a:

(0, 0), (1, 4), (2, 8)

The constant of proportionality is k in the equation of a proportional relationship, y = kx

y = 4x

Constant of proportionality: 4

Part b:

y = (1/3)x

Let x = 0, 3, 6 (one at a time)

For x = 0, y = (1/3)(0) = 0

For x = 3, y = (1/3)(3) = 1

For x = 6, y = (1/3)(6) = 2

Answer to part b:

(0,0), (3, 1), (6, 2)

Constant of proportionality: 1/3

Part c:

y = 0.5x

Let x = 0, 4, 8 (one at a time)

For x = 0, y = (0.5)(0) = 0

For x = 4, y = (0.5)(4) = 2

For x = 8, y = (0.5)(8) = 4

Answer to part b:

(0,0), (4, 2), (8, 4)

Constant of proportionality: 0.5

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
