Given the graph of a scatterplot and a trend line, explain how you would find the equation of the trend line.

To find the equation of a trend line, It is important to find the X axis and Y axis, Once x axis and y axis  is found if there is an association between x axis and y axis, We use linear equation to produce the trend line. Linear regression or algorithm called as OLS (Ordinary least square). Y= mx +c

y = dependent variable, x = independent variable , constant = c , m  = y2-y1/x2-x1.

Step-by-step explanation:

Scatter plot is to find association of two different variable.Trend line is the equation between xaxis and y axis.Prediction is best way to form equation.Linear regression y=mx +c Equation helps in predictive modelling between next best form. Y is a dependent variable or example sales.X can be n number of variable involved in the association rule.Linear regression is starting phase of data analysis.C = constant there is a certain point, where system has been started.Stock market did not start from 0 it started at a certain point.

Just a question- could you organize the data better? i just cannot tell which number are for which bakery. i will be happy to answer this question if you could do this for me! : )
