What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a fixed point, while reflection flips it over a line.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and have the same slope.
