Front

What is a function?

Back

A function is a relation where each input (x-value) corresponds to exactly one output (y-value).

Front

What is the result of a 180-degree rotation of a point (x, y)?

Back

The result is (-x, -y).

Front

How do you find the slope of a line using a calculator?

Back

Front

What does it mean for a situation to be proportional?

Back

A situation is proportional if the ratio between two quantities remains constant. For example, if there are 42 gallons in each barrel, the total gallons in x barrels is proportional.

Front

Which transformation does not preserve congruence?

Back

Dilation does not preserve congruence.

Front

What is the slope-intercept form of a linear equation?

Back

Front

What is the definition of a proportional relationship?

Back

A proportional relationship is one where the ratio of the two quantities is constant.

Front

What is the difference between reflection and rotation in geometry?

Back

Reflection flips a shape over a line, while rotation turns a shape around a point.

Front

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

Back

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a shape but not its shape.
