Apply Pythagorean theorem to find the length in between (2,1) and (6,9). Round your answer to the nearest hundredths.

1 answer

To find the distance between two points (x1, y1) and (x2, y2) using the Pythagorean theorem, we use the formula:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates are (2,1) and (6,9), so the formula becomes:

Distance = √((6 - 2)^2 + (9 - 1)^2)

Simplifying inside the square root:

Distance = √(4^2 + 8^2)

Calculating:

Distance = √(16 + 64)

Distance = √80

Rounding the answer to the nearest hundredths:

Distance = 8.94

Therefore, the distance between (2,1) and (6,9) is approximately 8.94.
