Corrections - Distance, Midpoint, and Parallel/Perpendicular

Front

What is the formula to find the midpoint between two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

Front

How do you find the endpoint of a segment when given one endpoint and the midpoint?

Back

Use the formula: Endpoint = (2 * Midpoint) - Given Endpoint.

Front

What is the equation of a line that is perpendicular to another line with slope m?

Back

The slope of the perpendicular line is -1/m.

Front

What is the midpoint between (3, -1) and (7, -5)?

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)
