Lesson 8 Variation

Math Response

Type the equation, using "y=" and no spaces.

Deg^°

Rad

y=mx is the most basic form of variation. You have heard of it as slope many times. What makes this different is there is no "b" or "y-intercept" that we discuss. Why? Simply put we are discussing how one variable affects the other.

You have been working with variation since day 1 of algebra 1....

Type answer...

Notice for the last two types in the table there is no graph pictured... Why is that?

Four major types of variations

Open Ended

Why is there no graph depicted in the last two types of variations?

Example 1A variation is:

Example 1B variation is:

Example 1C variation is:

Multiple Choice

Example 1A equation should look like:

$y=\frac{40}{x}$

$y=40x$

$z=40xy$

$z=\frac{40}{x}y$

$z=\frac{40}{y}x$

Multiple Choice

Example 1B equation should look like:

$y=\frac{8}{x}$

$y=8x$

$z=8xy$

$z=\frac{8}{x}y$

$z=\frac{8}{y}x$

Let's work through this one together

Dropdown

Example 2A: The variation equation is

, y =

when x = 15, and finally, x =

when y = 72.

Read the question carefully for context clues.

Try this one on your own

Dropdown

Example 2B: The variation equation is

, y =

when x = 3, and finally, x =

when y = 2.

Let's add another dimension...

Poll

Rate your understanding on a scale of 1-5 how you feel you understood variation.

5 - Easy peasy!

4 - It's understandable enough

3 - I feel I need more practice

2 - Definitely felt a little lost today but starting to grasp it

1 - I did not understand what was happening other than it looked like magic....
