**Hint**: The given simple problem can be solved easily. To find out the coordinates of a point Q and R in the above coordinate system Begin at the point and follow a vertical line either up or down to the x-axis. There is your x-coordinate. And then do the same but following a horizontal line to find the y-coordinate. after identifying Values of the coordinates write them in a pair of round brackets and a comma between them.

**:**

__Complete step-by-step answer__In a given coordinate system we have to find the coordinates of the points Q and R

First let us find the coordinates of point Q:

We know that the general form of the coordinate point is of the form \[(x,y)\] so

The x-axis value of point Q is \[ - 2\] and the corresponding y axis value of point Q is \[2\]

Therefore, the coordinates of point Q is \[( - 2,2)\]

let us find the coordinates of point R:

We know that the general form of the coordinate point is of the form \[(x,y)\] so

The x-axis value of point R is \[4\] and the corresponding y axis value of point R is \[ - 1\]

Therefore, the coordinates of point R is \[(4, - 1)\]

**Note**: The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located.
