Front

What is the relationship between the number of pages read and points earned?

Back

For every 125 pages Daysha reads, she earns 5 points. This represents a linear relationship.

Front

How do you find the scale factor in dilation?

Back

The scale factor is found by dividing the coordinates of the dilated point by the original point's coordinates. For example, from (8, 12) to (2, 3), the scale factor is 2/8 = 1/4.

Front

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

Back

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

Front

What does dilation do to a figure?

Back

A dilation produces a figure with proportional sides and congruent angles, maintaining the shape but changing the size.

Front

What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, b) where b is the y-coordinate.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

What does it mean for figures to be similar?

Back

Similar figures have the same shape but may differ in size; their corresponding angles are equal and their sides are proportional.

Front

How do you graph a linear equation?

Back

To graph a linear equation, identify the y-intercept and use the slope to find another point, then draw a line through these points.

Front

What is the formula for calculating the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the definition of a linear relationship?

Back

A linear relationship is one in which there is a constant rate of change, represented graphically as a straight line.
