How do you calculate the distance between two points in a coordinate plane?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What does 'r' represent in geometry?

Back

r represents the radius of a circle.

Front

What is the relationship between the slope and the angle of a line?

Back

The slope is equal to the tangent of the angle that the line makes with the positive x-axis.
