Answer:
13
Step-by-step explanation:
Since 5 is positive and 8 is negative, then you can just add the two.
5 + 8 = 13
Or use the distance formula:
Distance = [tex]\sqrt{(x_{2} - x_{1}) ^{2} + (y_{2} - y_{1})^{2} }}\\\\\sqrt{(7 -7) ^{2} + (5 - (-8)) ^{2}}\\\\\sqrt{0 + 169} \\\\Approximately 13\\[/tex]
