We study tables, charts, and graph, in particular we study distance-time graphs and speed-time graphs.

In our earlier classes (Math 7), students should have learned the basics of reading, interpreting and graphing of tables, charts, and graphs, as well as working with distance-time graphs.

So we focus on study speed-time graphs which can contain more information about the motion of an object than that of a distance-time graph.

With a speed-time graph, we can calculate acceleration, as well as calculating distance traveled, which is the area under the speed time graph.

We continue with multi-variable polynomial factorization. The specific topic is the Factor Theorem of multivariable polynomial.
