Slope Review Dec 24

The y-intercept is the point where a line crosses the y-axis. It is represented as the value of y when x = 0.

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

The y-intercept is the value of y at the point where the line crosses the y-axis.

The slope is 2, which indicates that for every 1 unit increase in x, y increases by 2 units.

The slope can be calculated using the formula (y2 - y1) / (x2 - x1) using two points on the line.

A positive slope indicates that as x increases, y also increases, showing an upward trend.

A negative slope indicates that as x increases, y decreases, showing a downward trend.

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

To find the slope from a graph, select two points on the line, determine the rise (change in y) and run (change in x), and apply the slope formula.

The slope of a horizontal line is 0, indicating no change in y as x changes.
