Question: What is the distance between the points (-2, -3) and (2, 1)?

Options:

Correct Answer: 5.66

Solution:

Using the distance formula: d = √((2 - (-2))² + (1 - (-3))²) = √(16 + 16) = √32 = 4√2 ≈ 5.66.

What is the distance between the points (-2, -3) and (2, 1)?

Step 1: Identify the coordinates of the two points. The first point is (-2, -3) and the second point is (2, 1).
Step 2: Use the distance formula, which is d = √((x2 - x1)² + (y2 - y1)²). Here, (x1, y1) is (-2, -3) and (x2, y2) is (2, 1).
Step 3: Substitute the values into the formula: d = √((2 - (-2))² + (1 - (-3))²).
Step 4: Simplify the expressions inside the parentheses: d = √((2 + 2)² + (1 + 3)²).
Step 5: Calculate the values: d = √(4² + 4²).
Step 6: Calculate the squares: d = √(16 + 16).
Step 7: Add the results: d = √32.
Step 8: Simplify √32: d = √(16 * 2) = √16 * √2 = 4√2.
Step 9: If needed, approximate the value: 4√2 ≈ 5.66.
