Answer:
#19: x=3
#20: would be n=4 i think
Step-by-step explanation:
#19- there are 4 x's and 12 +1's so 4 into 12 is 3.
#20- well the answer that i got was 5 but 4 was closer to 5 so yea.
i sure hope this helps!
Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:

Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
