Answer:
[tex]d=\sqrt{197}}[/tex]
Step-by-step explanation:
Use the distance formula to find the distance between two points.
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]
Plug in your coordinate points into x and y.
[tex]d=\sqrt{(9-8)^{2}+(7-(-7))^{2}}[/tex]
Solve for d.
[tex]d=\sqrt{(1)^{2}+(14)^{2}}[/tex]
[tex]d=\sqrt{197}}[/tex]
