1.How to plot cordanates?
2.how to find a rule of sequence?

Angelica:::How to plot cordanates? umm you have a 5x5 grid and your given the numbers (2, 1) go along 2 and up 1 then mark with a dot or an 'x' ???

1.how to plot if u have a 10x 4x graph say if u have a cord to plot example. (2.3) then go across 2 and up 3 and put a dot or x ect and then you have just ploted?
2.how to find a rule of sequence example. 2,4,6,8,10 how many to get to 4 from 2 is 2 so the rule is always add 2 for this task?

1.HOW TO PLOT COORDINATES. if you have a 10x10 and the numbers are for example (8,9),(1,7) and (10,1) then you must use the X axis (horizontal line) for the first number and go across until you find the number that you are looking for, and for the second number you must use the Y axis (vertical line) and find the number you are looking for there. Once you have found them put a X or a dot where they meet and reapet for the other numbers and as you draw the X/dots you must draw a line connecting to the last and if you followed these steps correctly you should see a picture.

2.HOW TO FIND THE RULE OF A SEQUNCE. to find the rule of a sequence you must first have a sequence for example. 2,4,6,8,10 to find the rule you must first find out the patternof the sequence and this patterns sequence is add two to the previous number which is pretty much the rule but you could also say it like this t=2n.

1.How to plot cordanates?
Lets say you had a grid 10 by 4, and you had to plot (3,4). You would go along the to 10 untill you reach 3, and then go up 4. Mark with a *. That is how you plot co-ordinates!
2.how to find a rule of sequence?
Use some colour, pictures and diagrams!
You find a sequence by having a pattern: 2,4,6,8,10. So you would find the rule looking at the difference between each no/previous number. Like 2,4 how numbers in between and there 2 and then check the next sequence. It is 4,6 how many between, and there2 and so on. so the sequence is 2 in between each set of numbers/previous numbers! Also that is called a rule!:)

1) How to plot co-ordinates?
Well first you have to draw up a grid. Lets say it was 10 by 10. and you had to find where (5,3). First you would have to go along 5 and then go up 3. mark with a cross.

2) How to find a rule of a sequence?
Say you had the pattern: 1,5,9,13,17,21. You would have to find the rule by trying to find the difference between each number or how many numbers there are between each number. like in this sequence the difference between each number is 4. Because the difference between 1,5 is 4. then you check the next 2 numbers of the sequence and that is 4 and so on and so on. So the rule for this number is: adding 4 to the previous number.

1.How to plot cordanates?
coordplane.gif

First you have to draw up a grid.(10 by 10)
draw an x axis (across)
draw a y axis (going up and down)
origin in the middle

you need to plot (20,15)
The order always goes x axis then y axis
so go right of the origin (along the x axis) 20 spaces
then up 15 (along the y axis)

and mark the spot with a x or a spot

and thats how you plot

2.how to find a rule of sequence?

Pattern (n)
0
1
2
3
4
5
6
30
n
Matches

4
7
10
13





The top number (or n) of the table is the pattern number (3 = Pattern 3)
The bottom number equals how many matches in the pattern (Pattern 4 has 13 matches)

how to find out the rule of this pattern you look at the difference between each pattern
4,7,10,13
each time is +3
So the rest of the pattern goes
16,19
To find out the 0 term you go
the first term (4) - the difference (3) equals the zero term (1)
4-3=1
To find out how many matches will be in pattern 30 you go
30 (n) x 3 (difference)= 90
+1=
91
To work out the rule you go
3n+1
difference x n (the top number) + the zero term

1)How to plot co-ordinates ?
Ex: (5,-3)
First:Draw up grid.Write 1=>10 and -1 => -10
Second:Find where the numbers are and mark the cross
2)How to find a rule of a sequence?
Ex: 2 4 6 8 10 12
We just need add two to each
number
You just need to find how many number highest between this number with that number ......

How to plot co-ordinates;

First you have to draw up a grid.(20 by 20)

draw an x axis (across the left aka Horizontal)

draw a y axis (going up aka Diagonal)

origin is in very the middle

Next;

Ok, so you shall plot (13, 3)

The order goes x axis and then y axis no matter what.

so go right of the origin (along the x axis first always) 13 spaces

then up 3 (along the y axis second)

and mark the spot with a x, to plot your co-ordinates!
