Question
What is the distance between the points (13, -19) and (-10, -19) in the coordinate plane? A. 32 units B. 3 units C. 11.5 units D. 23 units
Answer
23 units
- Use the distance formula: d = sqrt((x2-x1)^2 + (y2-y1)^2)
- Plug in the values: d = sqrt((-10-13)^2 + (-19-(-19))^2)
- Simplify: d = sqrt((-23)^2 + (0)^2) = sqrt(529) = 23.
