A customer is buying bath towels and hand towels and can spend NO MORE THAN $100.

Which graph best represents the solution set for this inequality?

HINT: What words can help you decide if the shading should be UP or DOWN?

Which graph best represents the solution set for this system of inequalities?

$$x\ +\ y\ <\ 1$$

$$x+y\ \ge\ 2$$

HINT: LOOK AT THE SYMBOLS and think about how they would be shaded.

The tables of ordered pairs represent some points on the graphs of lines f and g. Which system of equations represents lines f and g?

HINT: Type the table in DESMOS and use $$y_1\sim mx_1+b$$

Marli has $1200 in her savings account.

She wants more than y amount in her account at the end of the year.

She withdraws $150 each month.

Which inequality represents this situation, where x is the number of months?

Which graph best represents the solution set of

$$y>3x-4$$

HINT: LOOK AT THE SYMBOL WHERE IS IT SHADED? WHAT KIND OF LINE?

The graph of 2x + 4y = 12 is shown on the grid. 

Which ordered pair is in the solution set of  2x + 4y ≥ 12 ?

HINT: would ≥ mean UP or DOWN??

Rewrite as y=

8x = -16 - 8y

The graphed system of linear equations shows the average attendance for two schools.

Estimate the solution in years

What is the solution to this system of equations?

$$2x+y=40$$

$$x-2y=-20$$

STEP 1: OVER AND UNDER

STEP 2: Graph both lines
