Multiple Choice

For this symbol,
$\ge$
do you shade above or below the line?

Multiple Choice

For this symbol,
$\le$
is it a solid line or a dashed line?

Multiple Choice

Choose the correct inequality for this graph.

$y>2x-3$

$y\ge2x-3$

$y<2x-3$

$y\le2x-3$

Graphing Linear Inequalities

Objective: Graph linear inequalities and determine solutions.

Graphing Equations and Inequalities

Graphs of inequalities are similar to linear equations because they both have points on a coordinate plane and a line connecting the points. However, a linear equation is ONLY the line but an inequality extends beyond that line.

y < -3x + 1

Graphing Linear Inequalities

The inequality symbol tells you to SHADE ABOVE or SHADE BELOW the line.

< or ≤ Shade BELOW

> or ≥ Shade ABOVE

y ≥ -3x + 1

Multiple Choice

x + y < -1

Multiple Choice

Graph 5x - 2y < 10

Multiple Choice

Which of the following is NOT a solution to the inequality graphed below?

(4, 3)

(-6, 0 )

(0, 0)

(0, 2)

Multiple Choice

Which of the following is a solution to the inequality graphed below?

(3, 2)

(2, -5)

(0, 0)

(-9, 4)

Multiple Choice

Write the linear inequality in standard form for this situation: Ms. Savva is ordering pizzas and breadsticks for a school party and has a budget of no more than $81. An order of breadsticks costs $7 and a pizza costs $13.

7x + 13y < 81

7x + 13y ≥ 81

7x + 13y ≤ 81

7x + 13y > 81

Multiple Choice

Write the linear inequality in standard form for this situation: In order to raise money to attend upcoming competitions, the Math Pentathalon team is selling apple cider and hot chocolate. They hope to make at least $240 by selling hot chocolate for $1 a glass and hot apple cider for $2 a glass.

x + 2y < 240

x + 2y > 240

x + 2y ≤ 240

x + 2y ≥ 240

Multiple Choice
