Which exercises should I discuss on the board? Do you have any questions about the theory?

Recap: 

you need your mobile phones

s = 15 - 3a
Is this a linear formula? How do you know?

s = 15 - 3a
The starting value (or y-intercept) is

1. 15
2. -3a
3. s
4. 3a

consecutive means

1. afnemend
2. stijgend
3. consequent
4. opeenvolgend

Formula:
d = -2c +10.
The corresponding graph is

1. rising
2. falling
3. horizontal
4. vertical

When the gradient in a linear formula is positive for example y = 4x -5, the corresponding graph is:

Ch 1.3 Making Linear formulas

Which graph is of a

real linear formula?

recap

Questions homework?

explanation making a formula

Formula: y = 3x -5

The y-intercept is:

1. 3
2. 3x
3. 5
4. -5

The general form of a linear formula is:

k = 15x + 34

The gradient is

1. 15
2. 15x
3. 34
4. there is none
