Answer:
The distance is between points (1,1) and (7,9) is 10
Step-by-step explanation:
The distance between two points (x1, y1) and (x2, y2) can be found by:
[tex]\sqrt{(x2-x1)^{2} + (y2-y1)^{2}}[/tex]
If you substitute the values:
[tex]\sqrt{(7-1)^{2} + (9-1)^{2}}[/tex] = [tex]\sqrt{6^{2} + 8^{2}}[/tex] = [tex]\sqrt{100}[/tex] = 10
