Patterning Types
Identify the pattern type: 5, 10, 15, 20
Linear
What is the pattern rule for: 5, 10, 15, 20?
Multiply by 5 OR +5 each time
Complete the table for y = x + 2 when x = 1
y = 3
What does each point represent on a scatter plot?
A pair of values (x, y)
In y = mx + b, what does m represent?To show the trend in the data
slope
Identify the pattern type: 5, 10, 15, 20
Exponential
Find the rule: 2, 5, 8, 11
+3
If x = 3, what is y for y = 2x?
y = 6
If points go up from left to right, the relationship is:
Positive correlation
In y = mx + b, what does b represent?
y - intercept
Red, Blue, Green, Red, Blue, Green…
Repeating
Write an expression for “3 more than a number n”
n + 3
y = 3x − 1 when x = 4
y = 11
If points go down from left to right:
Negative correlation
Rewrite in proper form: y + 4 = x
y= x - 4
A pattern goes: 50, 45, 40, 35
Shrinking linear pattern
Write a pattern rule for: 2, 6, 10, 14
4n - 2
If y = 5x and y = 20, what is x?
x = 4
What does no clear pattern mean?
No correlation
Rewrite in proper form: y + 4x = 10
y = −4x + 10
A pattern made using shapes or figures that follow a rule.
Geometric
Create a rule for a pattern that starts at 4 and increases by 6.
Start at 4, add 6 each time (or 6n − 2)
x- 1, 2, 3, 4, 5
y - 5, 7, 9, ?, ?
Find the missing values and the pattern rule
Missing values: 11, 13
Rule: 2n + 3
What is the purpose of a line of best fit?
To show the trend in the data
Complete the missing part of the question, then solve:
y = 2x + 3
“When x = ___, y = 11”
