To graph the equation \( x - y = 6 \) in the form \( y = mx + b \), we first need to rearrange the equation into slope-intercept form.

Starting with the equation:

\[ x - y = 6 \]

We can solve for \( y \):

\[ -y = -x + 6 \]

Multiplying through by -1 gives:

\[ y = x - 6 \]

This means that the slope \( m = 1 \) and the y-intercept \( b = -6 \).

Next, we can identify some points based on this equation. For example:

  • When \( x = 0 \): \[ y = 0 - 6 = -6 \quad \text{(Point: (0, -6))} \]

  • When \( x = 1 \): \[ y = 1 - 6 = -5 \quad \text{(Point: (1, -5))} \]

With these points (0, -6) and (1, -5), we can now analyze the provided options to find matches:

  • Graph 1 has the points (0, -6) and (1, -5), which perfectly matches our calculations.
  • Graph 2 has (0, -4) and (1, -10), which does not match.
  • Graph 3 has (0, 0) and (6, 6), which does not match.
  • Graph 4 has (0, 3) and (3, 2), which does not match.

Therefore, the correct graph is Graph 1: (0, -6) and (1, -5).
