What does it mean if a relationship is linear?
The relationship follows an expected order or sequence - eg a pattern.
What is a variable?
A symbol that is a placeholder for a specific value.
If Point A starts at (0, 0) and translates by (-1, -1) what is its new coordinate?
(-1,-1)
What is a mixed fraction?
-35 + (-40) =
-75
Bob watches tv for 1 hour on Tuesday, three hours on Wednesday, 5 hours on Thursday and 8 hours on Friday. Does his T.V watching habits represent a linear relationship?
no
Solve for X
x = 5 + 3. What is the value of x?
8
If Point A starts at (5, 12) and translates by (-5, 6) what is its new coordinate?
(0,18)
7 x 12 - (-5) =
89
-20 x 5 + (-30) =
-130
A straight line on a graph represents a linear relation?
A) no, it would not be linear.
B) Yes, it is linear
C) Not if the line is going down.
B)
Solve for S
8 + s - 3 = 5
Subtract 8 from both sides.
s - 3 = (-3)
Then, add 3 to both sides.
S = 0
What line does x = 0 represent?
The Y axis.
If point A starts at (-3, 8) and transforms 2 spaces right and 3 spaces down, what would its new coordinates be?
A' would be (-1, 5).
40 - (-10) x 3 =
70
Billy is a plumber. He makes 25$ an hour and an additional 40$ when he gets called to a house. What expression is correct?
A) M = 25h + 40
B) M = 65h
C) M = 40h + 25
A) M = 25h + 40
Solve for p
7 + p - 4 = 12
Subtract 7 from both sides.
You are left with p - 4 = 5.
Then, add 4 to both sides.
You are left with p = 9
What line does y = 0 represent?
The X axis
What rule do we use to help us subtract integers?
Keep Change Change.
-85 x (-1) + 3 - (-10) x 2 =
108
Bob owns a bakery. Bob sells 5 muffins an hour, and 10 cupcakes when the store opens.
What would the linear expression be for this equation?
S = 5h + 10
Solve for x
2x + 7 = 25
x = 9
Subtract 7 on both sides of the equation.
You are left with 2x = 18.
Divide both sides by 2.
You are left with x = 9.
Why is the line y = x diagonal?
The y and x value of any point on the line will have the same value.
What is volume?
The space inside a 3d object.
