Use the equation y - 5 = x/3 to fill in the missing values in the table below. When I put BLANK, it means that part of the equation is blank and you need to fill it in.

x: BLANK y: 1
x: -3 y: 4
x: 0 y: BLANK
x: 6 y: BLANK
x: BLANK y: 8

To fill in the missing values in the table using the equation \( y - 5 = \frac{x}{3} \), we'll rearrange the equation to express \( y \) in terms of \( x \):

\[ y = \frac{x}{3} + 5 \]

Now we can calculate the missing values based on the given \( x \) and \( y \) values.

  1. For \( y = 1 \): \[ 1 = \frac{x}{3} + 5 \] Subtract 5 from both sides: \[ 1 - 5 = \frac{x}{3} \implies -4 = \frac{x}{3} \] Multiply by 3: \[ x = -12 \]

So, the first row is \( x: -12, y: 1 \).

  1. For \( x = -3 \), find \( y \): \[ y = \frac{-3}{3} + 5 = -1 + 5 = 4 \] This confirms the value is correct.

  2. For \( x = 0 \), find \( y \): \[ y = \frac{0}{3} + 5 = 0 + 5 = 5 \]

So, the third row is \( x: 0, y: 5 \).

  1. For \( x = 6 \), find \( y \): \[ y = \frac{6}{3} + 5 = 2 + 5 = 7 \]

So, the fourth row is \( x: 6, y: 7 \).

  1. For \( y = 8 \): \[ 8 = \frac{x}{3} + 5 \] Subtract 5 from both sides: \[ 8 - 5 = \frac{x}{3} \implies 3 = \frac{x}{3} \] Multiply by 3: \[ x = 9 \]

So, the last row is \( x: 9, y: 8 \).

Now, compiling everything, the table looks like this:

  • \( x: -12, y: 1 \)
  • \( x: -3, y: 4 \)
  • \( x: 0, y: 5 \)
  • \( x: 6, y: 7 \)
  • \( x: 9, y: 8 \)

Here are the missing values:

\[ \text{First Row: } x = -12 \ \text{Third Row: } y = 5 \ \text{Fourth Row: } y = 7 \ \text{Fifth Row: } x = 9 \]
