Anyone know this? giving brainliest to person who’s correct first :)

b

Step-by-step explanation: you are doing slope intercept

I think it is the first graph.

Step-by-step explanation:

All the other graphs are going up.

So they can't be -3

So they don't match the equation.

But the first graph is going down.

So it must be it.

Hope I helped.

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!

so then what are you asking?
