• a ratio comparing two quantities with different units.

• a plane in which a verticle number line intersect at their zero points.

• the cost per unit.

ratio table

• the cost per unit

• a table with columns filled with pairs of numbers that have the same ratio

rate

• ratios that express the same relationship between two quantities.

• to place a dot at a point named by an ordered pair.

• a ratio comparing two quantities with different kinds of units.

unit price

• the cost per unit

• the horizontal line of the two perpendicular number lines in a coordinate plane

equivilent ratios

• the greatest of common factors of two or more numbers

• the smallest whole number greater than zero that is a common multiple

• ratios that express the same relationship between two quantities.

x-axis

• the horizontal line of the two perpendicular number lines in a coordinate plane

• a rate that is simplified so it has a denominator of 1

ordered pair

• a pair of numbers used to locate a point on a coordinate plane

• a comparison of two quantities by division

unit rate

• the first number of an ordered pair

ratio

• a comparison of two quantities by division

• the greatest of the common factors of two or more numbers

x-coordinate

• the first number of an ordered pair the x-coordinate corresponds to the number on the x-axis

• the second number of an ordered pair the y-coordinate corresponds to the number on the y-axis
