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 negative 2 comma 2 right parenthesis, and left parenthesis 0 comma 1 right parenthesis.

To graph the linear equation \(y = -3x + 2\), we need to find a couple of key points on the line.

  1. Find the y-intercept: When \(x = 0\): \[ y = -3(0) + 2 = 2 \] So, one point is \((0, 2)\).

  2. Find another point by choosing a value for \(x\): Let's pick \(x = 1\): \[ y = -3(1) + 2 = -1 \] The second point is \((1, -1)\).

Now we have two points: \((0, 2)\) and \((1, -1)\).

Graphing these points:

  • Plot the point \((0, 2)\) on the graph.
  • Plot the point \((1, -1)\) on the graph.

Draw the line:

  • Draw a straight line that passes through both points and extends in both directions, with arrows on each end.

Analyzing the options you provided:

  • The correct response should be the one that shows a downward sloping line that passes through the points \((0, 2)\) and \((1, -1)\).

Looking through your descriptions, the closest matching response is: "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: (0, 2) and (1, -1)."

This matches our calculated points and accurately describes the graph of the equation \(y = -3x + 2\).
