Answer:

The distance between A=(1,1) and B=(7,-7) is 10.

Step-by-step explanation:

If you have two points A=(x_{1},y_{1}) and B=(x_{2},y_{2}) the distance between those points is  the length of the segment that separates them. And the formula of that distance is:

d(A,B)=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

Then the distance between A=(1,1) and B=(7,-7) is:

x_{1}=1\\y_{1}=1\\x_{2}=7\\y_{2}=-7

d(A,B)=\sqrt{(7-1)^2+((-7)-1)^2}\\d(A,B)=\sqrt{6^2+(-8)^2}\\d(A,B)=\sqrt{36+64}\\ d(A,B)=\sqrt{100} \\d(A,B)=10

The distance between A=(1,1) and B=(7,-7) is 10.
