**linear algebra How to get the equation of a line**

Good morning Matlab community, I have a matrix A(171000,2) and I plotted the data as shown in the attached figure. I do need to derive the equation of the curve/line and I am pretty sure it is not linear, more like quadratic.... Linear regression is a mathematical method that can be used to obtain the straight-line equation of a scatter plot. Start by placing your data into a table. For this example, let …

**linear algebra How to get the equation of a line**

Finding the Equation of a Line from Its Graph Suppose you are given the graph of a line in the coordinate plane, and asked to find its equation. If you can find the y -intercept and the slope , you can write the equation in slope-intercept form (unless, of course, it's a vertical line .)... Linear regression will only give you a reasonable result if your data looks like a line on a scatter plot, so before you find the equation for a linear regression line you may want to view the data on a …

**How to get an equation of a line/curve from a data set**

For example, if the equation of the line is: y = 1 y = 1 y = 1, the equation will look like a horizontal line that is parallel to the x x x-axis. There is no run, or rise. There is no run, or rise. In this case, you'll find that the slope is not positive or negative. how to find the right job quiz Use the points (1,3) and (2,1) to find the equation of an example line. The first number in the pair is the x coordinate the second number in the pair is the y coordinate.

## How To Get The Equation Of A Line

determine the equation of the line from such a plot. If however, we take the logarithms of both sides of the equation, we get : log y = m log x + log k Note that this is the equation of a straight line! That is, the logarithms of x and y have a linear relationship. If we wanted to, we could take the logs of all our data points, plot them on arithmetic graph paper, fit a straight line, and

- This line has some slope value (though not a value of "2", of course, because this line equation isn't solved for "y="). I'll first need to find the slope of the reference line.
- You're already familiar with the idea of the equation of a line in two dimensions: the line with gradient m and intercept c has equation y=m\,x+c. When we try to specify a line in three dimensions (or in n dimensions), however, things get more involved.
