Slide 4 -Quizvraag

Par. 3.1 Theory A: The graph of a linear function
By the end of the lesson you should be able to draw the graph of a linear formula.

The graph of a linear function is a straight line.
To draw the graph, you make a table with three points.
The book says two, we make three. Just to be sure.

Slide 5 -Tekstslide

How to draw a linear graph (copy!)
1. Write down the formula
2. Draw a table like this:
3. Choose 0 for x, calculate y:
4. Choose two different numbers for x and calculate y again
for example:
5. Draw a coordinate plane (a.k.a. set of axes)
6. Plot the three points
7. Draw a straight line through the three points.

Slide 6 -Tekstslide

1. Describe a linear formula
2. Give an example of a linear formula
3. Explain the steps to take when asked to draw a linear formula

In the equation
when

y=21x+3
x=4
y=
A

Slide 8 -Quizvraag

Let's draw one line of ex. 4 together
• Write down the formula: y = 2x - 3
• Make a tabel with x and y and three columns
• Fill in 0 for the first x
• Calculate y for x = 0
• Choose two different values for x and calculate the y
• Draw a coordinate plain
• Plot the three points and draw the straight line through them
