§6.3 Linear formulas
In this Lessonup
+    linear graphs and
+    linear formulas are dealt with

Slide 3 -Tekstslide

Formula:      number of visits x 3 + 6 = amount
Statement 1:
The graph for this formula is a straight line.

Slide 4 -Tekstslide

St. 1: This graph is a straight line.
A
true
B
false

Slide 5 -Quizvraag

8
It is a straight line indeed,
as you see alongside.
We call this a LINEAR GRAPH!
Time for a joke.

Slide 6 -Tekstslide

8
So a STRAIGHT LINE
is a LINEAR GRAPH
and it has a
LINEAR FORMULA !

Slide 8 -Tekstslide

number of visits x 3 + 6 = amount
Statement 2:
The roles that is played by the numbers 3 and 6 are the same.

Slide 9 -Tekstslide

St. 2: The roles are the same.
(Explanation next slide.)
A
true
B
false

Slide 10 -Quizvraag

It will be clear by now that
the numbers 6 and 3

ANS

Slide 12 -Tekstslide

The STARTING VALUE IS ...
A
20
B
10

Slide 13 -Quizvraag

Slide 14 -Tekstslide

Homework time
Do §6.3 now,

1. make  2. correct   3.picture     4. send in in GC
By the way, this  §  isn't that much work. Only one graph to be drawn.
Lucky you!
