Front

What is a transformation in geometry?

Back

A transformation is a change in the position, size, or shape of a figure. Common types include translations, rotations, reflections, and dilations.

Front

What does the notation (x+8, y+4) represent?

Back

It represents a translation of a point 8 units to the right and 4 units up in the coordinate plane.

Front

What is the diameter of a circle?

Back

The diameter is the distance across the circle through its center, equal to twice the radius.

Front

If the radius of a circle is 10, what is the diameter?

Back

The diameter is 20, since diameter = 2 * radius.

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities maintain a constant ratio or relationship to each other.

Front

How can you identify a proportional graph?

Back

A proportional graph is a straight line that passes through the origin (0,0).

Front

What does it mean if a graph is non-proportional?

Back

A non-proportional graph does not pass through the origin and does not maintain a constant ratio between the variables.

Front

What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two variables using dots to represent data points.

Front

What does a linear scatterplot indicate?

Back

A linear scatterplot indicates a straight-line relationship between the two variables.

Front

What does a nonlinear scatterplot indicate?

Back

A nonlinear scatterplot indicates a curved relationship between the two variables.
