Graphing Linear Inequalities with Two Variables

Tell whether the ordered pair is a solution of the inequality.

• Yes, it is a solution

• No, is is not a solution

Choose the correct inequality for this graph.

Choose the correct inequality for this graph.

Transform 3𝑥 − 2𝑦 < 7 into slope- intercept form.

• 𝑦 < 3/2 𝑥 + 7/2

• 𝑦 > 3/2 𝑥 + 7/2

• 𝑦 > 3/2 𝑥 − 7/2

• 𝑦 > 2/3 𝑥 − 7/3

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
