In the plan, there is one and only one straight line through two points. In a system (O,`vec(i)`,`vec(j)`) of the plan, it is possible
from the coordinates of two points to find the equation of a line
from the **coordinates of two points to find the equation of a line**.

The calculator allows to **find the equation of a straight line** (of the form y=ax+b) from the coordinates of two points by specifying the calculation steps.

This calculator is able to determine the equation of a straight line through two points with different abscissa, but also the equation of a straight line through two points with the same abscissa.

This example shows how to calculate the equation of the line that passes through the points of coordinates A[3;0] and B[2;5] , after calculation the result `[y=15-5*x]` is returned.

For example, to **calculate the equation of the straight line** through the points A[3;2] et B[3;3]
enter equation_straight_line(`[3;2];[3;4]`),
after calculation the result `[x=3]` is returned.

In some cases the calculator after determining the **equation of the straight** line from two points will propose to **draw straight line**
associated with this equation.
For that, when it is possible, it is enough to click on the link which appears in the area of detail calculations.

equation_straight_line(point1;point2)

equation_straight_line(`[3;1];[2;5]`) returns [y=13-4*x]
