# Grad Function

Calculates the gradient (slope) of a straight line

### Description

The function \(Grad\) calculates the gradient (slope) of a straight line between two points in the coordinate system.
The end points of the lines are defined with their X / Y coordinates or two objects of the class Point.

### Syntax

Grad (x1, y1, x2, y2)

Grad (Point(x,y), Point(x,y))

### Example

Grad(Point(1,1),Point(2,5))= 4

### Use of class Point

By using the \(Point \) objects, the distance can also be calculated with arguments other than \(x / y \).
The class \(Point \) contains its own methods for calculating the properties.

Suppose only the x-coordinates are known. \(y \) is unknown, but the angles from the 0 point can be determined.
In this case, the x-coordinate and the angle can be used as the point. An example of this can be found in the description of the Funbktion Distance.
