#### Equation of a trend line

## How do you calculate a trend line?

Lesson SummaryStep 1: Complete each column of the table.Step 2: Calculate the slope (m) of your trend line by dividing the total for Column 3 by the total for Column 4.Step 3: Calculate the y-intercept (b) of your trend line using the average of the slope from Step 2 and the average of the x- and y-coordinates.

## How do you describe a trend line?

A trend line is a line added to a scatter plot that shows the generalization of all the data. Let’s look at the scatter plot used in this explanation to show a trend line.

## What is a trend give an example?

## How do you describe a trend in a graph?

TrendsA trend is a pattern in a set of results displayed in a graph.In the graph above, although there is not a straight line increase in figures, overall the trend here is that sales are increasing.In this graph, the trend is that sales are decreasing or dropping.

## What is a trend line in math?

more A line on a graph showing the general direction that a group of points seem to follow.

## Which is the equation of a trend line that passes through the points?

The general formula for a line is y=mx+b, for which m is the slope, b is the y-intercept, x is any x value and y is any y value. By looking at the equation of the trend line, you can determine the y-intercept. For example, if the equation of the trend line is y=2x+5, the y-intercept is 5.

## How do you find the equation of a regression line?

The Linear Regression Equation The equation has the form Y= a + bX, where Y is the dependent variable (that’s the variable that goes on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the slope of the line and a is the y-intercept.
