The two points given are A(-5, -2) and B(4, -1).
The basic formula for calculating the distance between two points like these is given as
AB = √(x2 - x1)² + (y2 - y1)²
Where x1 = -5, x2 = 4, y1 = -2 and y2 = -1
The distance becomes;
AB = √(4 - [-5])² + (-1 - [-2])²
AB = √(4+5)² + (-1 + 2)²
AB = √(9² + 1²
AB = √81 + 1
AB = √82
AB = 9.05538
AB = 9.055 (Rounded to 2 decimal points)
