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

Slide 1 - Tekstslide

Slide 2 - Tekstslide

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

Slide 3 - Tekstslide

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

Slide 4 - Quizvraag

8
It is a straight line indeed,
as you see alongside.

Time for a joke.

Slide 5 - 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 6 - Tekstslide

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

Slide 7 - Quizvraag

Above 
Above you clearly see that 6 and 3 play a completely different
role in the graph!

Slide 8 - Tekstslide

Important:
+   when a graph is a STRAIGHT LINE it is called a LINEAR GRAPH
+   the formula of a linear graph is called a LINEAR FORMULA

Slide 9 - Tekstslide

Statement 3:
The graph that corresponds to this formula is a straight line.

Slide 10 - Tekstslide

St. 3: The graph for:
time x time + 1 = height
is a straight line.
(Explanation follows.)
A
false
B
true

Slide 11 - Quizvraag

Above you see that the graph is certainly no straight line.
By the way, this formula and graph are very similar to exercise 14  from paragraph 6.2!
 time x time + 1 = height 
If you got this wrong, study §6.2 once more!

Slide 12 - 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!
