Multiple Choice

What is an "x" value considered?

• input

• output

• range

• potato

Open Ended

Write the following into a sentence in English

-2x - 3 = y

Multiple Choice

What is y?

• output

• input

• domain

• potato

We can choose values for x when we choose a value, we can find y.

Let's fill out the following table.
Graph the points given!

-2x - 3 = y

Making a Table to Fill Out

x

(x,y)

y

-2x - 3

Labeling

Fill out the table to the right using the following equation!

y = 2x+5

Multiple Choice

What operation is happening in the following?

$$\frac{1}{4}$$

• Addition

• Subtraction

• Division

• Multiplication

Multiple Choice

True or False: The following things are the same, just written differently

$$\frac{1x}{4}\ =\frac{1}{4}x$$

• True

• False

Here when we choose a value of x, we should make sure that value is divisible by 4

If we don't we will end up with a fraction!

Choosing Appropriate Domains

x

(x,y)

y

Labeling

I've given you values! Just do the middle three for the following.

$$y=\frac{3}{5}x\ -2$$

Graphing

Plot 5 points for the following equation. Use values -2 to 2 for your x values.

y= 4 + 2x
