Question

Calculate the distance between the points F=(-5,9) and J =(-1, 4) in the coordinate plane.

Give an exact answer (not a decimal approximation).

Answer 1

√41

Explanation:

The distance formula is expressed as;

D = √(y2-y1)²+(x2-x1)²

D = √(4-9)²+(-1+5)²

D = √(-5)²+4²

D = √25+16

D = √41

Hence the required distance between F and J is √41
