NettetSimple Linear Regression: It is a regression model that represents a correlation in the form of an equation. Here the dependent variable, y, is a function of the independent variable, x. It is denoted as Y = a + bX + ε, where ‘a’ is the y-intercept, b is the slope of the regression line, and ε is the error. NettetExample: Plot a graph for a linear equation in two variables, x - 2y = 2. Let us plot the linear equation graph using the following steps. Step 1: The given linear equation is x - 2y = 2. Step 2: Convert the equation in the form of y = mx + b. This will give: y = x/2 - 1. NettetA linear equation in one variable is an equation with the exponent 1 on the variable. These are also known as first‐degree equations, because the highest exponent on the variable is 1. All linear equations eventually can be written in the form ax + b = c, where a, b, and c are real numbers and a ≠ 0. trials guild eso
