  • Distance Formula: d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point A (2, -1)

Point B (-4, 2)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>.

  1. Substitute [DF]:                    d = \sqrt{(-4-2)^2+(2+1)^2}
  2. Subtract/Add:                       d = \sqrt{(-6)^2+(3)^2}
  3. Exponents:                           d = \sqrt{36+9}
  4. Add:                                      d = \sqrt{45}
  5. Simplify:                               d = 3\sqrt{5}
