Which expression shows how to find the distance between points M(-5, -3) and N(2, 3)?

Solution
The distance between two points in a plane can be calculated using the distance formula derived from the Pythagorean theorem. The distance between points M(x1, y1) and N(x2, y2) is given by:
d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
Given the points M(-5, -3) and N(2, 3), we can substitute these values into the formula:
d = sqrt[(2 - (-5))^2 + (3 - (-3))^2] d = sqrt[(2 + 5)^2 + (3 + 3)^2] d = sqrt[(7)^2 + (6)^2] d = sqrt[(49) + (36)] d = sqrt[85]
So, the distance between points M and N is sqrt[85] or approximately 9.21 units.
