What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis. It represents the value of y when x is 0.

Front

What is a scaled copy?

Back

A scaled copy is a shape that is the same shape but different sizes.

What is a reflection in geometry?

Back

A reflection is a type of transformation where a figure is 'flipped' over a line of symmetry, producing a mirror image.

What is the line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.
