In mathematics an AXIS is

1. een as
2. een bijl
3. een deodorant
4. een snijpunt

A point in a coordinate system is given by its coordinates. Of P(9,12) the horizontal coordinate is

1. 12
2. 0
3. 9
4. both 9 and 12

A point of intersection is:

1. een kruispunt
2. een snijpunt
3. een nulpunt
4. een startpunt

The coordinates of S are: S(...,...)

S(3,16)

Explanation 3.2 Origin & grid points

(0,0) is known as  THE ORIGIN

grid points:

D(3,4) IS a grid point

Is (3, 2.5) a grid point?

Line segment:

PQ is a LINE SEGMENT

A line doesn't stop 

(=> it continues infinitely)

zigzag

Time for HW (and more explanation)

Evaluation

> Is Q(2,3.5) a grid point?

> What are the coordinates of the Origin?

End of schoolday: prayer & clip

3.3 Reading graphs part 2

Whiteboards: coordinate system and line/line segments

Draw a coordinate system with:  (pencil.... and geo triangle)

axis x and axis y from -4 -> +4

Plot point A(1,4)  , B (2, 4) and  C(3,1)

Draw a line segment AC and a line through points B  and C

Whiteboards: Variable and units

Ander voorbeeld:

Note in your Notebook:

1. Draw the horizontal and the vertical axis  (use pencil!)

2. right steps (equal on 1 axis!)

3. Names along axes (plural of axis)

4. Draw points 

5. Draw graph (fluently)
