Problem
What is the approximate distance between the points (1, -2) and (-9, 3) on a coordinate grid?
Step-by-step solution
Using the distance formula $d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$, we get $d = \sqrt{(-9-1)^2 + (3-(-2))^2} = \sqrt{(-10)^2 + (5)^2} = \sqrt{100+25} = \sqrt{125} \approx 11.18$.
Answer
11.18 units
