Solve each proportion
Please grab a new warm up!
Did you write down the homework?
Why are most baseball games held at night?
Because the bats sleep during the day
For most people, the ratio of the
length of their head to their total
height is 1:7. Use proportions to test
your measurements and see if they
match this ratio.
One week to our final!!!!!!!!!!
Get the Point!
You usually call me a
The numbers to the right of my zero are always______________.
The numbers to the left of my zero are always______________.
You can think of me as a
The numbers above my zero are always______________.
The numbers below my zero are always______________.
What do you get when you cross a number line with a thermometer?
In a coordinate plane the “number line” is called the _______________.
In a coordinate plane the “thermometer” is called the _______________.
There are 4 Quadrants on a coordinate plane!!
2/12 is the same as 4 to 24 is the same as 6 to 36….etc. So, this varies proportionally!
1/6 is not the same as 2/8 or 3/10 or ……….
A direct-variation equation is always linear and always contains the point (0, 0).
The variables x and y either increase together or decrease together.
Ms. Evans Example: Movie tickets and the total amount of money it’s going to cost
Zero Tickets=Zero dollars
The more movie tickets I buy, the more total money I will have to pay!
Think of a situation that has a direct Variation!
Y = kx
Find k when:
a. Y = 3x b. x=3y
c. y=5x d. x=5y
The equation below can be used to determine how many boys, y, are in sixth-grade class that has x girls. Y=5/6x
If there are 12 girls in the class, how many boys are in the class?
a. 8 b. 10 c. 12 d. 18
