Graph the linear equation by plotting points. \[ x+y=-2 \] Use the graphing tool to graph the equation.

Step 1 ：Set x to 0 and solve for y in the equation \(x+y=-2\). This gives \(y=-2\).

Step 2 ：Set y to 0 and solve for x in the equation \(x+y=-2\). This gives \(x=-2\).

Step 3 ：Plot the points (0,-2) and (-2,0) on a graph.

Step 4 ：Draw a line through the points (0,-2) and (-2,0). This line represents the graph of the equation \(x+y=-2\).

Step 5 ：\(\boxed{\text{The graph of the linear equation } x+y=-2 \text{ is a straight line that passes through the points (-2,0) and (0,-2). The line extends infinitely in both directions.}}
