Kitty [74]3 years ago

Answer:

3rd option

Step-by-step explanation:

A direct variation is expressed in this form:

y = kx

1. y - 4x = 8

y = 4x + 8 is not a direct variation

2. y + 2 = 7x

y = 7x - 2 is not a direct variation

3. y - 3x = 0

y = 3x is a direct variation

4. y = 5x - 2

y = 5x - 2 is not direct variation

I need help!!!!!!!!!!!!
Ainat [17]

Answer:

See explanation below.

Step-by-step explanation:

A number bond shows what two parts add to make the number. The 1 in the bigger circle is equal to the two small circles each 1/2.

On the number line you have drawn from 0 to 1 a bar. This is the whole number. Divide the bar with one line exactly at the half.

This now shows that two bars or 1/2 + 1/2 becomes 1 big bar or 1. This shows the same relationship as the number bond.
