A straight line has several properties that you
can measure or calculate. One of the property is
In this lesson, you'll get to know how to
formulate and calculate the slope of a line.
Also, note that the slope is also known as
This lesson is divided into 2 parts. The first part is
to help you
familiarize with the terms 'change in x' and
change in y'.
The second part is the actual lesson on the slope of a line.
When calculating the change, always 'run' first and then 'climb' up. The math video will illustrate more.
Know how to calculate the 'change in x' and
'change in y' first before attempting
to calculate the slope. This minimizes
Now, what is the definition for the slope of a
line? It is defined as the ratio of the 'change in y' to the 'change in x'. This simply means that you just divide 'change in y' with 'change in x' to find the slope.
