Question

If (-2, y) lies on the graph of y = 3x, then y = -9 -6 1/9

Answer 1

-6

Explanation:

Plug in -2 for x in the equation y=3x

Answer 2

Answer: Second Option

`y = -6`

Explanation:

We have the following equation

`y = 3x`

We know that point (-2, y) belongs to the graph of y

Then to find the value of the coordinate and substitute the point in the equation and solve for y

`y = 3(-2)`

`y = -6`

Finally we have that
`y = -6`

Note:

If the equation you wanted to write is:

`y = 3 ^ x`

So the value of y is:

`y = 3 ^(-2)\\\\y = (1)/(3^2)\\\\y = (1)/(9)`
