**Why is the Slope value delayed?**

It is a normal phenomenon that the glope will delay to show on the screen.

As the value will be calculated based on the Vertical height and Horizontal distance.

**How is the Slope calcuated ?**

Gradient is a measure of how steep a slope or a line is.

Gradients can be calculated by dividing the vertical height by the horizontal distance.

The greater the gradient the steeper a slope is.

The smaller the gradient the shallower a slope is.

To calculate the gradient of a slope the following formula and diagram can be used:

**Example :**

Gradient is usually expressed as a simplified fraction. It can also be expressed as a decimal fraction or as a percentage.

The slope of a line can be 'seen' to be sloping uphill or to be sloping downhill.

The examples so far have been sloping uphill as you look at the diagrams from left to right.

When a line is sloping uphill from left to right the gradient is given a positive value.

When a line is sloping downhill from left to right the gradient is given a negative value.
