You find two perfect points (exactly on a point) and use the formula
y2-y1 over x2-x1
scatter plot and line graph
A straight line which best describes the data on a scatter plot is called a "line of best fit". The line could pass through some of the points, all of them, or none of them.
Two variables are negatively correlated when the slope of the best-fit line that is drawn on the scatter plot with the independent variable on the x-axis and the dependent variable on the y-axis is negative.
It is called the line of best fit
It is very useful and interesting to be able to enter data for two variables, graph those points in a scatter plot, and then generate a line of best fit through those points. From the line of best fit, it is fairly simple to generate a linear equation. A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions.
It guarantees that the slope and intercept are minimized.
Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.
The line of best fit is simply the line that shows the general direction of the graph. The trick is to make the line go through as many points on the graph as possible. Some scatter plots have no line of best fit.
You have to put a line of best fit onto the graph and find where that line crosses the y-axis.
It is to find the line of best fit for the co-relation of data
By finding the line of best fit and using the straight line equation formula.
scatter plot and line graph
If the slope of a line is m then the slope of an altitude to that line is -1/m.
A straight line which best describes the data on a scatter plot is called a "line of best fit". The line could pass through some of the points, all of them, or none of them.

Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight.
