Question

Find the distance between (0,-2), (-5,-1)

Answer 1

`\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\(\stackrel{x_1}{0}~,~\stackrel{y_1}{-2})\qquad(\stackrel{x_2}{-5}~,~\stackrel{y_2}{-1})\qquad \qquadd = √(( x_2- x_1)^2 + ( y_2- y_1)^2)\\\\\\d=√([-5-0]^2+[-1-(-2)]^2)\implies d=√((-5-0)^2+(-1+2)^2)\\\\\\d=√((-5)^2+1^2)\implies d=√(26)\implies d\approx 5.099`
