"At Least" / "Minimum"

$\geq$

"Less Than" / "Under"

$<$

Pizza Budget

"You have at most $20.00 to spend on lunch."

Write the inequality:

Point Guard Stats

"The player scores more than 5 points but no more than 15 points per game."

Write the compound inequality (Middle X):

Unit 8.1: Graphing Systems

"The solution to a system is the Intersection Point where the lines cross."

Equation 1:

y = 1x + 2

Equation 2:

y = -1x + 4

Solution Coordinate:

( , )

Unit 8.2: Substitution

"Substitution means replacing a variable with its equal value."

CLUE A

y = 2x

CLUE B

x + y = 6

Step 1: Replace 'y' in Clue B with '2x':

x + ( ___ ) = 6

Step 2: Solve for X (Remember: x + 2x = 3x):

3x = 6 → x = __

Step 3: Solve for Y (Double your X):

y = 2 × ( __ ) → y = __

Unit 8.3: Elimination

"Elimination means adding the rows to cancel a variable out."

x + y = 10

x - y = 2

y cancels!

Step 1: Add the Rows (x + x = 2x):

2x =

Step 2: Solve for X (Divide by 2):

x =

Step 3: Solve for Y (x + y = 10):

y =
