Winter CBA Review

Front

What is the slope in a linear equation?

Back

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

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, indicating the value of y when x is 0.

Front

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

Back

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

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean to 'meet' the standard in a test score?

Back

To 'meet' the standard typically means scoring between 59% and 84% on the test.

Front

What is the range of scores for 'masters' level performance?

Back

'Masters' level performance is typically defined as scoring 86% or higher.

Front

If a student answers 15 questions correctly out of 20, what is their percentage score?

Back

Percentage score = (15/20) * 100 = 75%.

Front

What is the difference between 'approaches' and 'meets' in test scoring?

Back

'Approaches' is scoring between 38% and 56%, while 'meets' is scoring between 59% and 84%.

Front

What does it mean if a student feels 'terrible' about their confidence in a CBA?

Back

It indicates a low level of confidence in their understanding or preparation for the assessment.

Front

What is a common way to express a slope of 1/4?

Back

A slope of 1/4 means that for every 4 units you move horizontally, you move up 1 unit vertically.
