The required distance is the hypotenuse of a right triangle with sides of lengths [2 - (-1)] and [4 - (-3)] = 3 and 7 respectively. From the Pythagorean theorem, this distance is the square root of the sum of the squares of the lengths of each side, in this instance the square root of (9 + 49) or the square root of 58. There is no integral square root, but the decimal approximation is about 7.616 units.

Answer: 1
If you mean points of (1, -2) and (-9, 3) then the distance is about 11 units using the distance formula
since you know of one points and the halfway point between the other point. just multiply the halfway point by 2 and this is the total distance between the two points.
Points: (-1, -9) and (4, -2) Distance: (-1-4)2+(-9--2)2 = 74 and the square root of this is the distance which is about 8.602 to 3 decimal places

To find the distance between two points on a graph, you can use the distance formula: √((x₂ - x₁)² + (y₂ - y₁)²). Plug in the coordinates of the two points to calculate the distance.
To find the actual distance between two points on Earth using a graphic scale, measure the distance between the two points on the map using the scale provided. Convert this measurement to actual distance by using the ratio scale (e.g., 1 cm = 100 km) provided on the map. Multiply the measured distance by the ratio to find the actual distance between the two points on Earth.

Use Pythagoras to find the distance between two points (x0,.y0) and (x1, y1): distance = √(change_in_x² + change_in_y²) → distance = √((x1 - x0)² + (y1 - y0)²) → distance = √((4 - 1)² + (-1 -2)²) → distance = √(3² + (-2)²) → distance = √(9 + 9) → distance = √18 = 3 √2
Points: (1, -2) and (1, -5) Distance: 3 units by using the distance formula
Answer: 1
Points: (-6, 1) and (-2, -2) Distance: 5 units
(3-1)2 + (5-8)2 = 13 and the square root of this is the distance between the points
The distance between the points is two times the square root of 3.
Points: (2, 1) and (14, 6) Distance: 13
Distance = (9-5)2+(-6-1)2 = 65 and the square root of this is the distance between the points which is about 8.062257748
