Find the distance between points C (- 4; 7) and D (2; 8).
In order to find the distance between points C (- 4; 7) and D (2; 8), we use the formula:
d (СD) = √ ((x2 – x1) ^ 2 + (y2 – y1) ^ 2).
Substituting the known values x1 = – 4, y1 = 7, x2 = 2, y2 = 8 into the formula, we get:
d (СD) = √ ((x2 – x1) ^ 2 + (y2 – y1) ^ 2) = √ ((2 – (- 4)) ^ 2 + (8 – 7) ^ 2) = √ (6 ^ 2 + 1 ^ 2) = √ (36+ 1) = √37;
Answer: d (CD) = √37.
