Question

Remmi wrote the equation of the line y=1/3(x+2) He solved for x and got x=3y-2 Which of the following is an equivalent equation for x?

a. x=y-11/3
b. x=y+7/3
c. x=3(y-2/3)
d. x=3(y+2/3)

Answer 1

Just took the quiz.

The answer is x=3(y-2/3)

Answer 2

Option c is correct

`x = 3(x - (2)/(3))`

Explanation:

Remmi wrote the equation of the line :

`y = (1)/(3)(x+2)`

Multiply both sides by 3 we have;

`3y = x+2`

Subtract 2 from both sides we have;

`3y-2 = x`

or

x = 3y-2

We can write this as:

`x = 3(x - (2)/(3))`

Therefore, the following is an equivalent equation for x is,
`x = 3(x - (2)/(3))`
