simultaneous equations

today we extended the linear graph topic to include solving simultaneous equations using the intersection point. Below is the class notes from the lesson.

\
the skills you need are to be able to graph linear functions and read coordinates.

Or for practise go to the system of equations under the year 9 topic list and have a turn

Simple functions

For the past 2 weeks we have been looking at function. Last week Linear function was the focus and y=mx+c a key part of that. The students are expec5ted to be able to identify gradient and y-intercpets from graphs and write an equation in this form.
This week has seen us move to quadratics. Key terminology included, roots, line of symmetry, y-intercpets, turning points and nature of a parabola. The class has also been finding the equation from a table of values.
Below are some fo the class notes for the students to review in trhie own time.
