Final answer:
To find the distance between the points (6, 8) and (-5, -2), apply the distance formula to obtain √221, which is approximately 14.866 units.
Step-by-step explanation:
To calculate the distance between two points on a Cartesian plane, you can use the distance formula derived from Pythagorean theorem. The distance 'd' between two points with the coordinates (x1, y1) and (x2, y2) is given by: d = √((x2 - x1)2 + (y2 - y1)2).
For the points (6, 8) and (-5, -2), you plug them into the formula to get the distance:

The exact distance is √221, which is approximately 14.866 units.
