To determine the gradient of an angle, we can use the following formula: gradient = arctan(y/x) * 180/π where x and y represent the x-axis and y-axis coordinates of the angle in question, respectively. In this case, we have coordinates (-9,-27), which are in the third quadrant. Since these coordinates are in the third quadrant, the angle formed will have a value between 180 and 270 degrees. To determine the value of the gradient of the angle, we can use the formula above: gradient = arctan((-27)/(-9)) * 180/π = arctan(3) * 180/π = 71.5651 So, the angular gradient formed from coordinates (-9,-27) is approximately 71.5651 gradients.
