Algebra, T - Chart, and Linear Graph

1.) This diagram shows that a cabin with 1 room has 2 doors,

a cabin with 2 rooms has 5 doors, and a cabin with 3 rooms

has 8 doors.

Draw the next 2 cabins.

How many doors will a cabin with 10 rooms have?

~ 29 DOORS

Write an algebraic equation for this pattern.

~ 3x - 1 = y

2.) For this linear relationship y = 2x - 1. Complete

the following table of values.

Create a graph representing these values.

Describe a pattern in real life that the linear relation

y = 2x - 1 could represent. Make sure you explain what

both x and y represent.

eg.

There's a bag of chip that costs $2.00. I bought 2 bags of chip

(let's just say I bought 2 bags). I multiplied it by 2.

Then I remembered I have a coupon worth $1.00 off.

3 = 2(2) -1

SOLVE FOR HOMEWORK!

a.) 10 = x + 6 b.) x + 6 = 8 c.) x - 2 = 9 d.) x - 4 = 5

e.) 2x + 1 = 7 f.) 4x - 2 = 12 g.) x / 4 + 3 = 9 h.) x / 6 - 5 = 1
