The Scientist creates an equation that models her data for each tree so that she can predict the diameter in the future. select the linear equation that fits the data for tree 1, where x is the year and Y is the trunk diameter, in inches.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
