Question 405173


{{{d=sqrt((x[1]-x[2])^2+(y[1]-y[2])^2)}}} Start with the distance formula.



{{{d=sqrt((3-8)^2+(7-7)^2)}}} Plug in {{{x[1]=3}}},  {{{x[2]=8}}}, {{{y[1]=7}}}, and {{{y[2]=7}}}.



{{{d=sqrt((-5)^2+(7-7)^2)}}} Subtract {{{8}}} from {{{3}}} to get {{{-5}}}.



{{{d=sqrt((-5)^2+(0)^2)}}} Subtract {{{7}}} from {{{7}}} to get {{{0}}}.



{{{d=sqrt(25+(0)^2)}}} Square {{{-5}}} to get {{{25}}}.



{{{d=sqrt(25+0)}}} Square {{{0}}} to get {{{0}}}.



{{{d=sqrt(25)}}} Add {{{25}}} to {{{0}}} to get {{{25}}}.



{{{d=5}}} Take the square root of {{{25}}} to get {{{5}}}.



So our answer is {{{d=5}}} 



So the distance between the two points is  5 units.
