To solve the equation for y, we need to isolate the variable y on one side.

Starting with the equation 3x - 7y = 9:

First, subtract 3x from both sides: -7y = -3x + 9

Next, divide both sides by -7: y = (-3/7)x - 9/7

Now, we can plug in each value of x and find the corresponding value of y.

For x = -2:
y = (-3/7)(-2) - 9/7
y = 6/7 - 9/7
y = -3/7

For x = 0:
y = (-3/7)(0) - 9/7
y = 0 - 9/7
y = -9/7

For x = 2:
y = (-3/7)(2) - 9/7
y = -6/7 - 9/7
y = -15/7

Therefore, the values of y for x = -2, 0, and 2 are -3/7, -9/7, and -15/7, respectively.

Apologies for the incorrect response.

To solve the equation 3x - 7y = 9, we will isolate the variable y.

Starting with 3x - 7y = 9:
Subtract 3x from both sides:
-7y = -3x + 9

Next, divide both sides by -7 to solve for y:
y = (-3x + 9) / -7

Now, we can substitute the values of x to find the corresponding values of y.

For x = -2:
y = (-3(-2) + 9) / -7
y = (6 + 9) / -7
y = 15 / -7
y = -15/7

For x = 0:
y = (-3(0) + 9) / -7
y = (0 + 9) / -7
y = 9 / -7
y = -9/7

For x = 2:
y = (-3(2) + 9) / -7
y = (-6 + 9) / -7
y = 3 / -7
y = -3/7

Therefore, the values of y for x = -2, 0, and 2 are -15/7, -9/7, and -3/7, respectively.

I apologize once again for the incorrect response. Let's solve it correctly this time.

Starting with the equation 3x - 7y = 9:

To solve for y, we need to isolate y on one side of the equation. Let's start by subtracting 3x from both sides:

-7y = -3x + 9

Next, divide both sides by -7 to solve for y:

y = (-3x + 9)/(-7)

Now, we can substitute the given values of x (-2, 0, and 2) to find the corresponding values of y:

For x = -2:
y = (-3(-2) + 9)/(-7)
y = (6 + 9)/(-7)
y = 15/(-7)

For x = 0:
y = (-3(0) + 9)/(-7)
y = (0 + 9)/(-7)
y = 9/(-7)

For x = 2:
y = (-3(2) + 9)/(-7)
y = (-6 + 9)/(-7)
y = 3/(-7)

Therefore, the values of y for x = -2, 0, and 2 are 15/7, -9/7, and -3/7, respectively.

I apologize for the confusion. Let's solve the equation correctly.

We are given the equation: 3x - 7y = 9.

To solve for y, we need to isolate it on one side of the equation. Let's start by subtracting 3x from both sides:

-7y = -3x + 9.

Next, divide both sides of the equation by -7 to solve for y:

y = (-3x + 9)/(-7).

Now let's substitute the given values of x (-2, 0, and 2) to find the corresponding values of y.

For x = -2:
y = (-3(-2) + 9)/(-7)
y = (6 + 9)/(-7)
y = 15/(-7)
y = -15/7.

For x = 0:
y = (-3(0) + 9)/(-7)
y = (0 + 9)/(-7)
y = 9/(-7)
y = -9/7.

For x = 2:
y = (-3(2) + 9)/(-7)
y = (-6 + 9)/(-7)
y = 3/(-7)
y = -3/7.

Therefore, the values of y for x = -2, 0, and 2 are -15/7, -9/7, and -3/7, respectively.
