Given that the point P is on the image of the linear function y = - X-1, and the distance to the X axis is 2, the coordinates of P are obtained

Analysis: for the analytic formula y = - X - 1, know the value of a variable, you can find the value of another variable
When the distance from P to X axis is 2, we can see that the ordinate of point P is 2 or - 2. When y = 2, x = - 3, and when y = - 2, x = 1, so the P coordinate is (- 3,2) or (1, - 2)
