Question

Point C has the coordinates (–1, 4) and point D has the coordinates (2, 0). What is the distance between points C and D? units

Answer 1

Answer:

5 units

Step-by-step explanation;

We can use the formula for finding the length or magnitude of line joining two points.

Length = √((x2-x1)² + (y2-y1)²)

The points joining the line are C (-1,4) and D (2,0)

Length = √((2+1)² + (0-4)²)

            = √((3²) + (-4)²)

            = √ (9+16)

            = √25

            = 5 units
