A coordinate plane shows the x-axis ranging from negative 9 to 9 in increments of 1 and the y-axis ranging from 11 to negative 11 in increments of 1. A line with arrows at both ends joins two plotted points. The coordinates of the plotted points are as follows: left parenthesis 0 comma negative 4 right parenthesis, and left parenthesis 1 comma negative 10 right parenthesis.

To graph the equation \(x - y = 6\) using the form \(y = mx + b\), we first convert the equation into slope-intercept form (which is \(y = mx + b\)).

Starting with the original equation: \[ x - y = 6 \]

We can isolate \(y\): \[ -y = -x + 6 \]

Multiplying through by -1 gives us: \[ y = x - 6 \]

Now, in this equation \(y = x - 6\), the slope \(m\) is \(1\) and the y-intercept \(b\) is \(-6\).

To graph this equation:

  • Start at the y-intercept \((0, -6)\).
  • From there, use the slope: for every 1 unit you move to the right (positive direction on the x-axis), you move up 1 unit (positive direction on the y-axis).

You can also find another point by plugging in another value for \(x\):

  • If \(x = 3\): \[ y = 3 - 6 = -3 \] So another point is \((3, -3)\).

Plotting the points \((0, -6)\) and \((3, -3)\) and drawing a line through them gives the graph of the equation.

Given your descriptions, the correct image would be the one where a line drawn through points includes the coordinates (0, -6) as this corresponds correctly with our derived equation \(y = x - 6\).

The specific plotting of other points from your options does not seem to match the equation \(x - y = 6\) or \(y = x - 6\) correctly, so please refer to the graph that clearly shows that relationship. If you can provide those images or correct specific coordinates as needed, I can further assist!
