Slope Applications

Front

What is slope in the context of a graph?

Back

Slope is a measure of the steepness or incline of a line, calculated as the change in the vertical direction (rise) divided by the change in the horizontal direction (run).

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

Back

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

What is the y-intercept in a linear equation?

Back

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

What is the average rate of change and how is it calculated?

Back

The average rate of change is calculated as the change in the dependent variable divided by the change in the independent variable over a specific interval.
