M ( − 3 , − 9 ) N ( 4 , 8 ) MN = ( x N − x M ) 2 + ( y N − y M ) 2 MN = ( 4 + 3 ) 2 + ( 8 + 9 ) 2 = 49 + 256 = 305 = 17 , 5 L e n g t h o f t hi s se g m e n t i s e q u a l t o 17 , 5
To find the approximate length of line segment MN with endpoints at M(-3, -9) and N(4, 8), apply the distance formula in Coordinate Geometry for accurate measurements.
The approximate length of line segment MN can be found using the distance formula in Coordinate Geometry.
Step-by-step explanation:
Use the distance formula: √((x2 - x1)² + (y2 - y1)²)
Substitute the coordinates of M(-3, -9) and N(4, 8) into the formula
Calculate: √((4 - (-3))² + (8 - (-9))²)
It simplifies to: √(7² + 17²)
Further simplify: √(49 + 289) = √338
Approximately, the length of MN is √338 or approximately 18.39 units.
The length of line segment MN with endpoints M(-3, -9) and N(4, 8) can be calculated using the distance formula and is approximately 18.38 units.
