Module 5 Remediation (Exam Review)

Front

What is a negative correlation in a graph?

Back

A negative correlation indicates that as one variable increases, the other variable decreases. This is visually represented by a downward slope in the graph.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

How do you convert a point-slope form equation to slope-intercept form?

Back

To convert from point-slope form (y - y1 = m(x - x1)) to slope-intercept form (y = mx + b), solve for y.

Front

What does it mean if a graph shows no correlation?

Back

No correlation means there is no discernible relationship between the x and y values, and the points appear scattered without any clear pattern.

Front

How do you find the point from a point-slope equation?

Back

To find the point from a point-slope equation (y - y1 = m(x - x1)), identify (x1, y1) as the point on the line.

Front

What is point-slope form of a linear equation?

Back

Point-slope form is expressed as y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

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

How do you identify the slope from a graph?

Back

The slope can be identified by selecting two points on the line, calculating the rise (vertical change) and run (horizontal change) between them.

Front

What is the difference between standard form and slope-intercept form?

Back

Standard form is Ax + By = C, while slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is zero.
