In order to find the distance between two points we will use the next formula
[tex]d=\sqrt[]{\mleft(x_2-x_1\mright)^{2}+\mleft(y_2-y_1_{}\mright)^{2}}[/tex]where
(7,15)=(x1,y1)
(1,7)=(x2,y2)
we substitute the values
[tex]d=\sqrt[]{(1-7)^2+(7-15)^2}[/tex][tex]d=\sqrt[]{6^2+8^2}=\sqrt[]{100}=10[/tex]The distance between (7,15) and (1,7) is 10
