$(\frac{7}{8}, - \frac{1}{8})$ , $(- \frac{1}{8}, \frac{7}{8})$

Step 1

Use the distance formula to determine the distance between the two points.

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

Step 2

Substitute the actual values of the points into the distance formula.

$\sqrt{{((- \frac{1}{8}) - \frac{7}{8})}^{2} + {(\frac{7}{8} - (- \frac{1}{8}))}^{2}}$

Step 3.2.1

Subtract $7$ from $- 1$ .

$\sqrt{{(\frac{- 8}{8})}^{2} + {(\frac{7}{8} - (- \frac{1}{8}))}^{2}}$

Step 3.2.2

Divide $- 8$ by $8$ .

$\sqrt{{(- 1)}^{2} + {(\frac{7}{8} - (- \frac{1}{8}))}^{2}}$

Step 3.2.3

Raise $- 1$ to the power of $2$ .

$\sqrt{1 + {(\frac{7}{8} - (- \frac{1}{8}))}^{2}}$

Step 3.3

Multiply $- (- \frac{1}{8})$ .

Step 3.3.1

Multiply $- 1$ by $- 1$ .

$\sqrt{1 + {(\frac{7}{8} + 1 (\frac{1}{8}))}^{2}}$

Step 3.3.2

Multiply $\frac{1}{8}$ by $1$ .

$\sqrt{1 + {(\frac{7}{8} + \frac{1}{8})}^{2}}$

Step 3.4

Combine the numerators over the common denominator.

$\sqrt{1 + {(\frac{7 + 1}{8})}^{2}}$

Step 3.5

Step 3.5.1

Add $7$ and $1$ .

$\sqrt{1 + {(\frac{8}{8})}^{2}}$

Step 3.5.2

Divide $8$ by $8$ .

$\sqrt{1 + 1^{2}}$

Step 3.5.3

One to any power is one.

$\sqrt{1 + 1}$

Step 3.5.4

Add $1$ and $1$ .

$\sqrt{2}$

Step 4
