THE DISTANCE BETWEEN THE X POINTS IS 4-(-5)=4+5=9
THE DISTANCE BETWEEN THE Y POINTS IS -3-(-2)=-3+2=-1
THUS WE HAVE A TRIANGLE WITH SIDES 9 & 1.
TO FIND THE HYPOTENUSE WE USE THE PATHAGOREAN FORMULA A^2+B^2=C^2 (C^2 BEING THE HYPOTENUSE.
1^2+9^2=C^2
1+81=C^2
C^2=82
C=SQRT82
C=9.0553851 OR THE DISTANCE BETWEEN THESE TWO POINTS.
