Let's say that d is distance, and the formula is as follows;
d=[tex] \sqrt{(x_{2}- x_{1} ) ^{2}+ (y_{2}- y_{1} ) ^{2}[/tex]
This means that with the values filled in we have an equation that looks like;
[tex]d= \sqrt{(7-1)^{2}+(-7-1)^{2}} [/tex]
Therefore solving would look like;
[tex]d= \sqrt{(7-1)^{2}+(-7-1)^{2}}
d= \sqrt{(6)^{2}+(-8)^{2}}
d= \sqrt{36+64}
d= \sqrt{100} [/tex] or 10
