Let us calculate the distance between the two points (5,-7) and (9, 8)
- 7.5 units
- 15.5 units
- 17.5 units
- 20.5 units
Explanation
Explanation:
Let the given points be A(5,-7) and B(9,8)
A(5,-7) and B(9, 8)
Here,
X1 = 5 , Y1 = -7 and X2 = 9, Y2 = 8
By using the distance formula, we have
AB² = (X2-X1)² + (Y2-Y1)²
AB² = (9-5)² + (8-(-7))²
AB² = (4)² + (15)²
AB² = 16+225
AB² = 241
AB = ✓241 = 15.5 units.
Hence,
Distance between the points A(5,-7) and B(9,8) is 15.5 units.
