With this calculator you can determine the parameters a and b of the equation of a line y = m·x + b from the coordinates of two points (x1|y1) and (x2|y2). Alternatively, you may use the coordinates of one point and one parameter (a or b) or the whole equation of line as input. After the equation of the line has been calculated or typed in completely, the coordinates of other points (x3|y3) may be calculated when one of the coordinates (x3 or y3) is given.
Type the known values (coordinates or parameters of the equation of a line)
into the corresponding fields. A possible calculation is performed after the next
click on any free space of the window or the "calculate" button.
Fields of input values will be coloured light green while fields of output values
are coloured pink.
Two points have the coordinates (1|3) and (2|5). Type these values into the
corresponding fields. After a mouse click on a free space of the window or the
"calculate" button the equation of a line is calculated.
You get the result y = 2·x + 1.
