Positive linear association !
Answer:
1 - F
2 - B
3 - H
4 - A
Step-by-step explanation:
1.
m = -2
b = 4
y < mx + b
y < -2x + 4
F
2.
m = 1
b = -2
y < mx + b
y < 1x -2
y < x - 2
B
3.
m = -4
y <= mx + b
H is the only one that follows those rules
4.
m = 1
y >= mx + b
A is the only one that follows those rules
Step-by-step explanation:
the solution is in the picture
So the answer would be 8+9n≥80. The reason why is because he has $80 and he saved $8 and he earned $9 for each hour but we do not know how many hours so that is why it is n. and it says minimum so u might think that it might be ≤ but my sister says to think the opposite so the symbol will be ≥.
<u>Check: </u> <u>IT SAYS THAT N IS GREATER THAN 8 SO CHOOSE A NUMBER GREATER THAN 8 WHICH CAN BE 9.</u><u>
</u>
8+9n≥80
8+9*9≥80
8+81≥80
90≥80, so this makes sense.
