Question 87948
The formula for calculating distance between two points (x1,y1) and (x2,y2) is

={{{sqrt((x2-x1)^2 + (y2-y1)^2)}}}


So, distance betweem (-6,10) and (3,-2) will be

={{{sqrt((3-(-6))^2 + (-2-10)^2)}}}

={{{sqrt(9^2 + (-12)^2)}}}

={{{sqrt(9^2 + (-12)^2)}}}
={{{sqrt(81 + 144)}}}
={{{sqrt(225)}}}
