Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).
Step 1: d = StartRoot (negative 7 minus (negative 7)) squared + (negative 4 minus (negative 2)) squared EndRoot
Step 2: d = StartRoot (negative 7 + 7) squared + (negative 4 + 2) squared EndRoot
Step 3: d = StartRoot (0) squared + (negative 2) squared EndRoot
Step 4: d = StartRoot 0 + 4 EndRoot
Step 5: d = StartRoot 4 EndRoot
Therefore, d = 2.
