EOC ALGEBRA 1 REVIEW 1

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

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

The slope of the line is 2.

The slope of the line is -3.

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

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