Find the distance between the points A(2,3) and B(9,7).

Step-by-step solution

1. Compute the differences in x and y: $\Delta x=9-2=7$ and $\Delta y=7-3=4$.
2. Square these differences: $7^2=49$ and $4^2=16$.
3. Add the squares: $49+16=65$.
4. Take the square root: $\sqrt{65}$.
5. The distance between the points is $\sqrt{65}$.
