## How do you calculate best fit?

The line of best fit is described by the equation **ŷ = bX + a** where b is the slope of the line and a is the intercept (i.e. the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables and estimate the value of Y for any specified value of X.

**line drawn over pivot highs or under pivot lows to show the prevailing direction of price**. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price and also describe patterns during periods of price contraction.

## What is the line of best fit on a graph?

Line of best fit refers to **a line through a scatter plot of data points that best expresses the relationship between those points**. … A regression involving multiple related variables can produce a curved line in some cases.

## What is curve of best fit?

Curve of Best Fit: a curve **the best approximates the trend on a scatter plot**. If the data appears to be quadratic we perform a quadratic regression to get the equation for the curve of best fit. If it appears to be cubic then we perform a cubic regression.

## How do you calculate a trend?

To calculate the trend percentage for 2018 you have to divide $40 000 by $30 000 to get 1.33 and then multiply it by 100. The result which is 133% is your trend percentage for 2018. If the trend percentage is greater than 100% it means the balance in that year has increased over the base period.
