Answer:
7.81
Step-by-step explanation:
You may calculate the distance between two points with the following formula:
D= √((X₂-X₁)² + (Y₂-Y₁)²
Then, considering the given points:
P1: (3,1) P2: (-2,7)
You only have to replace those poins into the given formula:
D=√(-2-3)²+(7-1)²
Which will give us the final distance between above points: D=7.81
