What comes next?
-3, -10, -17, -24, ____

The slope of a a line that passes through (0, 5) and (12, 8) is...
3/12 AND/OR 1/4
Is this a sequence?
x: 2, 4, 6, 8, 10
y: -3, 0, 2, 5, 7
No!
Which of these has causation AND correlation?
A) "The soap has bubbles because my sister likes it that way."
B) "The soap has bubbles because it was used."
B!
A has correlation only.
Are the equations perpendicular?
1) f(x) = 10x - 16
2) f(x) = -1/10x + 23
Yes! They have opposite reciprocal (flipped) slopes.

4
What is a5 in this sequence?
-12, -8, -4, 0, 4, 8, 12.
4!
Does the following have strong or weak correlation?
"The hours you spend working out vs. how much you sweat in a day"
Strong! It makes sense.

Honey! (Miel)
The y-intercept of a line with a slope of 4 and a point of (7, 6).
Hint: use y = mx + b
-22
What is a14 in this sequence?
7, 9, 11, 13, 15...

If something has "r = 0.3", what is the correlation?
A) Strong Positive
B) Strong Negative
C) Weak Positive
D) Weak Negative
C!
Anything closer to 0 is weak! And 0.3 is positive!
