Linear interpolation equationThe linear interpolation equation is given by:y = y1 + (x - x1) * ((y2 - y1) / (x2 - x1))where (x1, y1) and (x2, y2) are the known data points, x is the unknown point's x-value, and y is the unknown point's y-value....
Regression equation = 1.6415 + 4.0943 x Linear Regression calculatoruses the least squares method to find the line of best fit for a sets of data `X` and `Y` or the linear relationship between two dataset. It estimates the value of a dependent variable `Y` from a given independent variabl...
Linear Interpolant Formula: The line through two points $A$ and $B$ in the two-dimensional Cartesian coordinate plane is given by the equation $$y=\frac{y_B-y_A}{x_B-x_A}(x-x_A)+y_A ,$$ where $(x_A,y_A)$ and $(x_B,y_B)$ are point coordinates of $A$ and $B$,...

Example 1: The formula for distance and rate of speed in physics is {eq}d = rt {/eq}, where d is distance, r is the rate, and t is time - this is a linear equation. Imagine a vehicle traveling at a constant rate of 30 miles per hour and driving a total of 120 miles. How ...
The calculator above will graph and output a simple linear regression model for you, along with testing the relationship and the model equation. Keep in mind that Y is your dependent variable: the one you're ultimately interested in predicting (eg. cost of homes). X is simply a variable us...
For Δy=y1-y0, we obtain Δy=Δx*f’(x0). In the limit that x approaches x0, the final equation becomes: L(x)≈f(x0)+f’(x)(x-x0) where L(x) represents the linear approximation to the function f(x) at the point x0. The calculator will calculate linear approximation to ...
Binary one-time equation calculator formula \(a1X + b1Y = c1\) \(a2X + b2Y = c2\) result: \(X=(c2b1 - c1b2)/(a2b1 - a1b2)\) \(Y=(a1c2 - a2c1)/(b2a1 - a2b1)\)
Linear regression calculator The linear regression calculator generates the linear regression equation. It also draws: a linear regression line, a histogram, a residuals QQ-plot, a residuals x-plot, and a distribution chart.It calculates the R-squared, the R, and the outliers, then testing the...
