A quadratic function would fit this data.
The data does not increase at the same rate each time, so it is not linear. It comes to a maximum at (8, 150) and decreases. It decreases the same way it increased. This would lead to a U-shaped graph, which indicates a quadratic function.
The tenth is the first number after the decimal which is 6. To see if it rounds up or stays the same, check the number before it which is 6 as well. 5 + a number you round up so 7.668 -> 7.7
Answer:
y will increase by 8
Step-by-step explanation:
y = 8x+2
We increase x by 1
Replace x with x+1
y = 8(x+1) +2
y = 8x+8+2
y = 8x+2 +8
y will increase by 8
The ordered pairs are of the form 
Therefore, the only ordered pairs that are of this form are
