Answer:

(-4, -1), (0, 2), (4, 5)

Step-by-step explanation:

(-4, -1): If you see the x-axis and trace -4 and -1 from the y-axis, they both lead to a point that is on the graph.

(-2, 1): The graph, at -2 on the x-axis, lies at height 0.5, so 1 is wrong.

(0, 2): At 0, the graph lies on 2.

(4, 5): At 4 on the x-axis, the graph lies at height 5.

(2, 0): The graph is already at height 3.5 when at length 2.

A,B,C,D i.e. all statements are true!

<u>Step-by-step explanation:</u>

According to question, Lynn works as a part-time vendor selling necklaces for $15 each and bangles for $10 each. She needs to earn a minimum of $300 per week to cover her expenses. The inequality for above scenario will be :

$15x + 10y\geq 300$ where, x is number of necklaces & y is number of bangles.

Lynn will meet her goal if she sells 12 bangles and 12 necklaces. i.e. x=12 and y=12 , putting values inequality : $15(12) + 10(12) = 300$ which follows inequality . True statement!

Lynn will meet her goal if she sells 20 bangles and 6 necklaces.

putting values inequality : $15(6) + 10(20) = 290$ which follows inequality . True statement!

Lynn will meet her goal if she sells 6 bangles and 12 necklaces. putting values inequality : $15(12) + 10(6) = 240$ , which follows inequality . True statement!

Lynn will meet her goal if she sells 2 bangles and 18 necklaces.putting values inequality : $15(18) + 10(2)=290$ , which follows inequality . True statement!
