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 $B$, respectively. ...
The trouble is, those points may not be exactly on the same line. One way to work around this is with the knowledge that the points must satisfy the same linear equation. For example, if you are given the linear equation y = 4x + 16, you know that the points (-4, 0) and (-1...
The 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....
Given:y = f(x) = 3x + 5 For x = -2, y = -1 For x = -1, y = 2 For x = 0, y = 5 For x = 1, y = 8 For x = 2, y = 11 Plot these points on the graph. Similarly, you can try the linear function calculator to compute the graph for the following linear functio...
