Detailed explanation-1: -A Line Graph is most frequently used to show trends and analyse how the data has changed over time. Line Graphs are drawn by first plotting data points on a Cartesian coordinate grid, and then connecting a line between all of these points.

Detailed explanation-2: -Trendlines, also known as lines of best fit or regression lines, graphically illustrate trends in data series and are commonly used when charting predictions. A trendline is typically a line or curve that connects or passes through two or more points in the series, showing a trend.

Detailed explanation-3: -How to Calculate the Trend Line. How does someone calculate the trend line for a graph? A trend line indicates a linear relationship. The equation for a linear relationship is y = mx + b, where x is the independent variable, y is the dependent variable, m is the slope of the line, and b is the y-intercept.

Detailed explanation-4: -Line charts, or line graphs, are powerful visual tools that illustrate trends in data over a period of time or a particular correlation. For example, one axis of the graph might represent a variable value, while the other axis often displays a timeline.
