Question

Find the distance between the points (4,-6) and (7,-6)?

Answer 1

Having 2 points of coordinates A(x1,y1) and B(x2,y2), then the distance AB is:

d=sqrt((x2-x1)²+(y2-y1)²)

Thus:

d=sqrt((7-4)²+(-6-(-6))²)=sqrt(3²+0)=3

Note: both points have the same y coordinate: -6. So the distance is just (x2-x1)=7-4=3
