Unit 4 Summative Practice

Front

What is the formula for calculating slope?

Back

Front

What does 'Rise over Run' mean in the context of slope?

Back

'Rise over Run' refers to the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line.

Front

What is the constant of variation in direct variation equations?

Back

Front

What is the y-intercept of a line?

Back

Front

What is a direct variation equation?

Back

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the change in x (run) is zero.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0 because there is no vertical change (rise) between any two points.

Front

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

Back

Front

What does it mean if the slope is negative?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What does it mean if the slope is positive?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.
