What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

How do you find the slope of a line from a graph?

Back

To find the slope, pick two points on the line, calculate the rise (change in y) over the run (change in x).

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

How can you determine if a function is linear from a table of values?

Back

A function is linear if the differences between consecutive y-values divided by the differences between consecutive x-values are constant.

What does it mean for a line to be increasing?

Back

A line is increasing if the slope is positive, meaning as x increases, y also increases.

Front

What does it mean for a line to be decreasing?

Back

A line is decreasing if the slope is negative, meaning as x increases, y decreases.

Front

What is the significance of a slope of 0?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

What is the significance of an undefined slope?

Back

An undefined slope indicates a vertical line, meaning x remains constant while y changes.
