Question

ok i need help

Answer 1

k

Answer 2

Well we know that X always goes up by 1, so for the x column, it would be 1,2,3,4,5 but for the y column, what is the pattern that you see between the numbers 1,5,9, and 13? I am also pretty sure you can include 1,5,9,and 13 into the y column.

Answer 3

wait what

Answer 4

What part are you confused on?

Answer 5

I am also pretty sure you can include 1,5,9,and 13 into the y column.

this part

Answer 6

So you see how Y has 1 already filled out in the first row? You can add 5,9, and 13 in the following rows because that is given.

Answer 7

ohhhh okk

Answer 8

Now we just need to know what value follows 13. What is the answer when you get 13-9? This is the number you add to 13 to get to the next y value.

Answer 9

(5,17)

Answer 10

Yes that is correct. Now you know what the common difference is between each of the y values, we just need to graph it now. When graphing can you just plot all the points from the table and draw a line through them?

Answer 11

ye hold on

Answer 12

Not quite, from you got the point (1,1) right, but the next point (2,5) is a bit off. Right now instead of (2,5) you have (2,4). And also please make sure that the dot on (1,1) is directly on (1,1)

Answer 13

the second one is on 2,5

Answer 14

the lines not tho

Answer 15

It just looks a bit off to me. I think it is because the point (1,1) where the dot is is a bit to high when you graphed it.

Oh like the software you are using says the second point is on (2,5) and the first point is on (1,1)?

Answer 17

yea

Answer 18

Ok that image looks a lot better and it looks correct to me.

Answer 19

Common difference is just the difference between the y values. The difference between all y values is the same, so what is 13-9? That is the common difference.

Answer 20

4

Answer 21

only thing is the last one says the slope

Answer 22

Remember the average rate of change formula? so y2-y1/x2-x1. Pick any 2 coordinates for example (1,1) and (2,5). Fill in the blanks of the formula. So Y2-y1 would just be subtracting both y values from the 2 coordinates which would be 5-1. For x2-x1, that would just be subtracting the x values from both the 2 coordinats which would be 2-1. What is (5-1)/(2-1)?

Answer 23

4

Answer 24

Yes that is correct. The slope is 4 which is also the same as your common difference.

Answer 25

thank you @ramen for helping me.

Answer 26

Np. Did you get it right?
