Solution
To find the distance between two points in a plane, we can use the distance formula which is derived from the Pythagorean theorem. The distance d between two points (x1, y1) and (x2, y2) is given by:
d = sqrt[(x2-x1)² + (y2-y1)²]
Here, our points are (-6, -2) and (2, 4). So, x1 = -6, y1 = -2, x2 = 2, and y2 = 4.
Substituting these values into the formula, we get:
d = sqrt[(2 - (-6))² + (4 - (-2))²] d = sqrt[(8)² + (6)²] d = sqrt[64 + 36] d = sqrt[100] d = 10
So, the distance between the points (-6, -2) and (2, 4) is 10 units.
