find the distance between two points on a plane. The points are (9,5) and (-2,2)
:
The distance formula: d = sqrt%28%28x2-x1%29%5E2+%2B+%28y2-y1%29%5E2%29%29
Assign the given values as follows
x1 = 9; y1 = 5
x2 =-2; y2 = 2
;
d = sqrt%28%28-2-9%29%5E2+%2B+%282-5%29%5E2%29%29
:
d = sqrt%28%28-11%29%5E2+%2B+%28-3%29%5E2%29%29
:
d = sqrt%28121+%2B+9%29%29
:
d = sqrt%28130%29%29
d = 11.4
