![]() The y-intercept, b, is found by plugging in x0 into the equation. where (x1,y1) and (x2,y2) are the coordinates of any two points in the line. For example, if you wanted to generate a line of best fit for the association between height and shoe size, allowing you to predict shoe size on the basis of a person's height, then height would be your independent variable and shoe size your dependent variable). Explanation: Any linear equation has the form of. ![]() ![]() To begin, you need to add paired data into the two text boxes immediately below (either one value per line or as a comma delimited list), with your independent variable in the X Values box and your dependent variable in the Y Values box. For this calculator, you need to input four different values namely x1, y1, x2, and y2. This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X. The line of best fit is described by the equation ลท = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). Slope-intercept form is applicable when you have the slope and y-intercept for a line or when you can calculate these for the line. This form is most useful when the slope and y-intercept of the line are known. This simple linear regression calculator uses the least squares method to find the line of best fit for a set of paired data, allowing you to estimate the value of a dependent variable ( Y) from a given independent variable ( X). The slope intercept form is a way of representing a linear equation in a two-dimensional coordinate plane.It defines the connection between two variables x and y in a straight line.
