========================================
Formula to find Distance:
========================================
[tex]\text{Distance = } \sqrt{X2-X1)^2 + (Y2-Y1)^2} [/tex]
========================================
Find Distance between (5, 9) and (7, -7):
========================================
X2 = 5, X1 = 7, Y2 = 9, Y1 = -7, therefore,
[tex]\text{Distance = } \sqrt{(9+7)^2 + (5-7)^2} [/tex]
[tex]\text{Distance = } \sqrt{(16)^2 + (2)^2} [/tex]
[tex]\text{Distance = } \sqrt{256 + 4} [/tex]
[tex]\text{Distance = } \sqrt{260} [/tex]
[tex]\text{Distance = } 16.12 \text{ units}[/tex]
========================================
Answer: 16.12 units
