Front

How do you find the slope of a linear function from a graph?

Back

The slope (m) is calculated as the rise over run, or the change in y divided by the change in x between two points on the line.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Front

What is the significance of the coordinates (0, b) in a linear function?

Back

The coordinates (0, b) represent the y-intercept of the function, where the graph crosses the y-axis.
