Question 74139
<pre>
Find the distance between each pair of points.
(-3, 0) and (4, 0)

There is not much information in the book about finding the distance between points and need some help. Thanks


To find the distance of the given points, 
 {{{d = sqrt ((y[2] - y[1])^2 + (x[2] - x[1])^2)}}}

Let (-3, 0) = ({{{x[1]}}},{{{y[1]}}})
    (4, 0)  = ({{{x[2]}}},{{{y[2]}}})

Substitute to the formula.

 {{{d = sqrt ((0 - 0)^2 + (4 - (-3))^2)}}}
      = {{{sqrt (0 + 7^2)}}}
      = {{{sqrt (49)}}}
    d = 7
