## Ratio, Rate, Unit Rate

**A comparison of two things with the same units.**

__Ratio:__EX: boys to girls (they are both people)

Can be written as a fraction, with the word "to" or with colons :

EX: 5/4, 5 to 4, 5:4

__A comparison of two things with different units.__

**Rate:**EX: Heart beats per minute (beats and minutes)

160 beats/2 minutes

__A rate with a denominator of 1, such as per minute, per second, per gallon, per__

**Unit Rate**:hour and so on.

52 beats/1minute

**Has a fraction in the numerator, denominator, or both**

__Complex Fractions:__EX: 1/2 over 2/3 <-- all one fraction

**If two quantities have a constant ratio or unit rate then they are**

__Proportional:__proportional.

__When the ratio is not constant__

**Nonproportional:****A grid that that contains two number lines that intersect at their zero**

__Coordinate Plane:__points or origins

**4 regions on the coordinate plane**

__Quadrants:__**Pair of numbers such as (1, 3) used to locate or graph points**

Ordered Pair:Ordered Pair:

**The number that corresponds with the x axis. It is the first number in an**

__X Coordinate:__ordered pair. (1, 3)

**The number that corresponds with the y axis. It is the second number in an**

__Y Coordinate:__ordered pair. (1, 3)

**: Runs vertically or up and down**

__Y-Axis__**: Runs horizontally or left and right**

__X-Axis__**The point (0, 0). It is directly in the middle, where the x and y axis intersect.**

__Origin:__**How one quantity changes in relation to to another.**

__Rate of Change:__**When the rate of change is the same between relations then**

__Constant Rate of Change:__it is said to be constant.
