Given the points:
C = (10, -1) → x = 10; y = -1;
D = (-6, 3) → x = -6; y = 3.
To find the distance CD, follow the steps below.
Step 1: Substitute the values in the distance formula.
Step 2: Solve the values inside the parentheses.
Step 3: Solve the square root and find d.
Answer: The distance CD is 16.5.
