Question

Which equation shows the relationship between x and y?

1. y = 3x

2. x = 3y

3. y = 3 + x

4. x = 3 + y

Answer 1

Answer:

y = 3+x is the answer ...hope it helps ..

Answer 2

All equations show the relationship. (I think) We have to find the equation, which satisfies the solutions given in the adjoined image.

Ans: 1. y = 3x

Justification:

• When y = 0:-

0 = 3x ⇒ x = 0. (Satisfies.)

• When y = 3:-

3 = 3x ⇒ x = 1. (")

• When y = 6:-

6 = 3x ⇒ x = 2. (")

• When y = 9:-

9 = 3x ⇒ x = 3. (")
