To calculate the distance between two points, use the Distance Formula. The Distance Formula: √((x₂ - x₁)² + (y₂ - y₁)²), where x₁, x₂, y₁, and y₂ are the x- and y-values of two given coordinates. The given coordinates are (-1, 3) and (8, 3). Let's plug them in and solve.√((x₂ - x₁)² + (y₂ - y₁)²)√((-1 - 8)² + (3 - 3)²)√((-9)² + (0)²)√(81 + 0)√819
Answer:
The distance between the points (-1, 3) and (8, 3) in the coordinate plane is 9 units.
