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.
Answer: To determine the equation, identify two points on the trend line. Calculate the slope between the two points. Use the slope-intercept form with the slope and one of the points from the line to determine the y-intercept. Write the equation with the slope and the y-intercept.
