#### Slide 2 -Tekstslide

Learning goals
I am able to draw the graph given a linear function.

I understand what a linear equation is.

#### Slide 3 -Tekstslide

Consider the function y = 1.5x - 1
Calculate y for x = 4

#### Slide 4 -Open vraag

What does this mean?
So, for function y = 1.5x - 1
if x = 4 then y = 5

numberCupid

#### Slide 5 -Tekstslide

What does this mean?
So, for function y = 1,5x - 1
if x = 4 then y = 5

Also written as (4, 5)

#### Slide 6 -Tekstslide

Consider the function y = 1.5x - 1
Calculate y for x = 0

#### Slide 7 -Open vraag

Consider the function y = 1.5x - 1
Calculate y for x = -4

#### Slide 8 -Open vraag

Now they're in a table!

#### Slide 9 -Tekstslide

Now they're in a graph.

Consider that it doesn't matter which pair of points you use to draw the line, you always end up with the same line.

#### Slide 10 -Tekstslide

Now they're in a graph :o.
