Front

What is the slope of a line?

Back

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

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

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

Front

How can you determine the equation of a line given two points?

Back

1. Calculate the slope using the two points. 2. Use one point and the slope to solve for b in y = mx + b.

Front

What is the significance of the slope being negative?

Back

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