Question

what is the distance between the points (-9, 4)and(3,-12) ? a. 12 units b. 16 units c. 20 units d. 28 units

Answer 1

20 units

Explanation:

Point 1 (-9, 4)

Point 2 (3, -12)

Distance Formula

d=√((x2-x1)²+ (y2-y1)²)

d=√((3+9)²+ (-12-4)²)

d=√(12²+ (-16)²)

d=√(144+ 256)

d=√400

d=20
