What is the y-intercept of y = 3x + 1 ?

• 1

• 3

• x

• y

The rate of change is ______.

• 2 blocks/1 step

• 2 blocks

• 2

• 2/1

Is this a LINEAR or NONLINEAR pattern?

• Linear

• Non-linear

Answer explanation

It is NON-linear! It does not have a constant rate of change.

How many blocks are in step 0?

• 5

• 1

• 4

• 9

What is the equation/rule for this pattern?

• y = 5x

• y = 1x + 4

• y = 4x + 1

• y = 4x + 5

What is the y-intercept for y = 2x - 4 ?

If the rate of change = 5 dots/1 step and step 0 = 6, what is the equation?

• y = 5x + 6

• y = 6x + 5

• y = 5/1

• y = 5/1 + 6

If the rate of change = 10 dots/1 step and step 0 = 1, what is the equation?

• y = 10x

• y = 1x + 10

• y = 10x + 1

• y = 10
