- Distance Formula:
Step-by-step explanation:
<u>Step 1: Define</u>
Point M(-21, -7)
Point N(-5, -7)
<u>Step 2: Identify</u>
M(-21, -7) → x₁ = -21, y₁ = -7
N(-5, -7) → x₂ = -5, y₂ = -7
<u>Step 3: Find distance </u><em><u>d</u></em>
Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>
- Substitute in points [Distance Formula]:
