DP:

• 2 exams (80%)
• IA (20%) (starts end this year)
• Always a formative before the summative
• Test week test always consist of 2 tests 

Grade:

0%-15%                        1

15%-30%                     2

30%-45%                    3

45%-55%                    4

85%-100%                   7

This term

• Chapter 1, 2
• No grade at the end of this term.
• We do have a test this testweek: 1 test with GDC, 1 test  without GDC.

Make exercise 1b.
(when finished early do 1a,1d,1e,1f,1h)

Forms of linear equations

Skills for linear equations

1. Given an equation determine its graph.
2. Given a graph (or some information about it) find its equation.
3. Determine wether two lines are parallel.
4. Determine wether two lines are perpendicular.

Given an equation determine its graph

Use the slope-intercept form

Given a graph (or some information about it) find its equation.

Use the point-slope form

When are two linear lines parallel?

Draw the graph of the following lines:

y=−2x+3

y=​2​​1​​x−1

Distance and midpoint

d=√​(x​2​​−x​1​​)​2​​+(y​2​​−y​1​​)​2​​​​​

(​2​​x​1​​+x​2​​​​,​2​​y​1​​+y​2​​​​)
