Problem 248

Find the distance between given points (-3, -7) and (-4, 15)

Solution

formula for distance is when two point

(x1,y1)and (x2,y2)are given

distance= $\sqrt{(x_{2}-x_{1})^{^{2}}+(y_{2}-y_{1})^{^{2}}}$

put all values in this formula

distance= $\sqrt{(-4-(3))^{^{2}}+(15 - (-7))^{^{2}}}$

distance= $\sqrt{(-4+3)^{^{2}}+(15 +7)^{^{2}}}$

distance= $\sqrt{(-1)^{2}+(22)^{^{2}}}$

distance= $\sqrt{1+484}$

distance= $\sqrt{485}$

distance=22.02
