Answer:
A
Step-by-step explanation:
In the inequality, you want to simplify it to get x on one side, and the numeric values on the other.
So, moving 9 to the other side, you get, 8x<-32
Then, you can divide by 8 on both sides to get x alone.
You get, x<-4.
From this, we can see that it should be an open dot at -4, and pointing to the left.
So, the correct number line is A.

Student c was close to average
Answer:
(0, 7), (1, 11), (2, 15)
Step-by-step explanation:
to find the y values, plug in the given x values into the equation y= 4x+7
when x = 0
y = 4(0) + 7
y = 0 + 7
y = 7
so the y value that corresponds to the x value 0 is 7 which is also written as (0,7)
when x = 1
y = 4(1) + 7
y = 4 + 7
y = 11
so the y value that corresponds to the x value 1 is 11; also written as (1, 11)
when x = 2
y = 4(2) + 7
y = 8 + 7
y = 15
so the x value 2 corresponds to the y value 15; also written as (2 , 15)
