Front

What is the slope of a line that crosses through the points (0, 2) and (-10, -16)?

Back

9/5

Front

For the line equation y = -2x + 3, what is the slope and y-intercept?

Back

Slope = -2, y-intercept = 3

Front

What is the definition of slope in terms of rise and run?

Back

Slope is known as rise/run.

Front

What is the translation rule for moving a point 2 units left and 3 units up?

Back

(x, y) → (x - 2, y + 3)

Front

What type of transformation is a reflection?

Back

A reflection is a transformation that flips a figure over a line.

Front

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

Back

Slope = (y2 - y1) / (x2 - x1)

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

How do you identify a translation in a graph?

Back

A translation shifts the graph horizontally and/or vertically without changing its shape.

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a figure over a line, while a rotation turns a figure around a point.

Front

What is the effect of a dilation on a figure?

Back

A dilation enlarges or reduces a figure proportionally.
