Find the distance between each pair of points.

(-3, 0) and (4, 0)

To find the distance of the given points, 

 d+=+sqrt+%28%28y%5B2%5D+-+y%5B1%5D%29%5E2+%2B+%28x%5B2%5D+-+x%5B1%5D%29%5E2%29



Let (-3, 0) = (x%5B1%5D,y%5B1%5D)

    (4, 0)  = (x%5B2%5D,y%5B2%5D)



Substitute to the formula.



 d+=+sqrt+%28%280+-+0%29%5E2+%2B+%284+-+%28-3%29%29%5E2%29

      = sqrt+%280+%2B+7%5E2%29

      = sqrt+%2849%29

    d = 7
