Question

Find the distance between the points (3, -1) and (4, 6).

Answer 1

distance formula so it is
`\sqrt[]{50}`

Answer 2

`\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{3}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{6})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√([4-3]^2+[6-(-1)]^2)\implies d=√((4-3)^2+(6+1)^2) \\\\\\ d=√(50)\implies d\approx 7.07`
