Interpreting Slope and Y Intercept

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

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

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

For every 1 unit increase in x, y increases by 2 units.

The slope of a horizontal line is 0.

The slope of a vertical line is undefined.

'm' represents the slope of the line.

'b' represents the y-intercept of the line.

By selecting two points on the line and using the slope formula: (change in y) / (change in x).

A negative slope indicates that as x increases, y decreases.
