As you can see, switching between these two forms of linear equations is not hard but nevertheless, it requires some calculations. Find the slope with the slope intercept formula m (y - y) / (x - x) (3-1) / (2-1) 2/1 2 3. Mean Geometric Mean Quadratic Mean Average Median Mode Order Minimum Maximum Probability Mid-Range Range Standard Deviation Variance Lower Quartile Upper Quartile Interquartile Range Midhinge Standard Normal Distribution. Write down the first point’s coordinates. Free perpendicular line calculator - find the equation of a perpendicular line step-by-step. 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. You will need the two points that go through your line. Explanation: Any linear equation has the form of. Just type numbers into the boxes below and the calculator (which has its own page here) will automatically calculate the equation of line in standard and slope intercept forms. We've found the slope-intercept form The slope equals -A/B, and the intercept equals -C/A. In the slope intercept form, find the line’s equation. 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). You can use the calculator below to find the equation of a line from any two points. Use slope intercept form calculator to find the equation of a straight line using slope intercept formula (function) ymx+b, two points, or one point and slope. 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. Write the following slope-intercept form equation of a line in standard form : y 3x + 1. 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 ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). 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).
