To find the distance between the points (-2, 1) and (4, 3), you can 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 (-2, 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: Square root of 40 = square root of \(c^2\) (c is the exponent).
-
Step 7: Square root of 40 is between square root of 36 and square root of 49, so between 6 and 7 - closer to 6, so about 6.3 units.
This sequence provides a systematic approach to finding the distance using the distance formula derived from the Pythagorean theorem.
