Standard A.CED.2 – Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.

Ohio specific:

a. Focus on applying linear and simple exponential expressions. (A1, M1)

b. Focus on applying simple quadratic expressions. (A1, M2)

c. Extend to include more complicated function situations with the option to graph with technology. (A2, M3)

Vocabulary for this standard: equation, variable, relation, ordered pair, graph, coordinate axis, x-axis, y-axis, scale, label

**ordered pair**is a pair of numbers, (x, y), written in a particular order.A

**graph**is a diagram representing a system of connections or interrelations among two or more thingsA

**coordinate axis**is one of the lines in the coordinate system that represents one of the dimensions (two-dimensional axes are represented by x and y)The

**x-axis**is the horizontal (left-right) axis of a system of coordinates and is the first number in an ordered pair.The

**y-axis**is the vertical (up-down) axis of a system of coordinates.**Scale**is the ratio of the size of a graph (model) to the actual size of the object represented.

A

**label**is a description of the x-axis, y-axis, and graph (with units of measurement) to identify what the graph describes.Which one doesn’t belong (WODB) –
