Graphing Linear Functions in Grade 10.

Graphing Linear Functions in Grade 10.

During the past week the Grade 10 Mathematics class has been practicing drawing Linear Functions, by using either the “Table Method” or “Intercept Method”. It really helps to visually see the relationship between the x and the y co-ordinates as they are plotted on the Cartesian Plane. A function is a mathematical rule by means of which each element of[Read More…]

Which side will the “x” be on in Linear Inequalities?

Which side will the “x” be on in Linear Inequalities?

The Grade 10 Mathematics students have recently been learning about Linear Inequalities. We have discovered that Inequalities are very similar to Equations but instead of finding just 1 or 2 solutions we can find infinitely many solutions to the problem. Also Inequalities contain a < or > sign whereas an Equation only has an = sign in the problem. For example[Read More…]

Using graphs to show data VISUALLY!

Using graphs to show data VISUALLY!

In Grade 10 Computer Applications Technology class we have been learning that you can enter data into an Excel worksheet and then visually represent it in the form of a graph or chart. Graphs are easier to understand and interpret than raw data, especially when you are working with large amounts of data. You can also compare various sets of[Read More…]
