Q & A

What is the formula for calculating the slope of a line?

The slope of a line is calculated using the formula \( \frac{y2 - y1}{x2 - x1} \), where \( y1 \) and \( y2 \) are the y-coordinates of two points on the line, and \( x1 \) and \( x2 \) are the corresponding x-coordinates.

What was the error in the original slope calculation mentioned in the transcript?

The error was in the division of the slope formula, which was corrected to 4 divided by 19, resulting in a slope of 0.21.

What is the significance of the slope value in the context of the transcript?

The slope value of 0.21 is significant as it is used to correct the coefficient of static friction in the graph, indicating the relationship between frictional force and the normal force.

How does the coefficient of static friction relate to the slope of the graph?
