Front

When a coordinate reflects over the y-axis the x-coordinate...

Back

changes to its opposite sign

Front

What is the distance between points (3, -5) and (3, -8)?

Front

What is a polygon?

Back

A closed figure formed by a finite number of straight line segments.

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (Base1 + Base2) * Height

Front

What does it mean to reflect a point over the x-axis?

Back

The y-coordinate changes sign, while the x-coordinate remains the same.

Front

What does it mean to reflect a point over the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

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

Back

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