To find the distance between the two points (-2, 1) and (4, 3), follow these steps in the correct order:
Step 1: Draw a right triangle by dropping a vertical side and a horizontal side.
Step 2: Determine the vertical side (2 units) and horizontal side (6 units) lengths by counting on the grid (be careful of the scale), or using the vertical coordinates (3 to 1) and horizontal coordinates (-2 to 4).
Step 3: Use the Pythagorean Theorem for right triangles to determine the diagonal length: \( 2^2 + 6^2 = c^2 \).
Step 4: \( 4 + 36 = c^2 \).
Step 5: \( 40 = c^2 \).
Step 6: \( \sqrt{40} = \sqrt{c^2} \).
Step 7: \( \sqrt{40} \) is between \( \sqrt{36} \) and \( \sqrt{49} \), so between 6 and 7 - closer to 6, so about 6.3 units.
