I seem to be stuck on these few questions, could anyone help me?? ty

4x

3x

Step-by-step explanation:

1.)

we see that when x=0 y=0 which means that our equation

y=mx+b

b=0

(this is shown if we plug in 0 for x)

0= 0x+b

0=b

Next, we notice that each time it's increasing by four which means our slope is just 4

the answer is 4x

The y intercept (or b) is the same deal as question one

we can also see that when x=1 y=3 which means that

3=x+0

3=x

our slope is 3

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

what the question so we can you out
