Graphing Relations

The "Origin" is another name for which ordered pair?

• (1, 0)

• (0, 1)

• (0, 0)

• (1, 1)

Answer explanation

The Origin is where the two number lines cross, when each has a value of 0. So (0, 0)

Will the graph of a proportional relationship go through the origin?

• Always

• Sometimes

• Never

Answer explanation

Proportional graphs ALWAYS pass through or start at the origin.

Is this graph proportional?

• No, it passes through the origin

• No, it is a single straight line

• Yes, it passes through the origin and is a single straight line

What tells us this is not a proportional graph?

• We don't know what number it starts at.

• It does not start at the origin

• But it IS proportional!

Proportional?

• Yes,

• No, its facing the wrong way

In math, we use a graph that shows positive and negatives in both axes- this is called:

• The standard form

• The cartesian plane

• The vector plane

• The carthigian plane

The x-axis represents the-

• dependent variable

• independent variable

• the codependent variable

The y-axis measures the:

• dependent variable

• independent variable

• nothing

Points on the graph are represented using

• Base Pairs

• Matched Pairs

• Ordered Pairs

• Math Pairs

Which point is represented here

• (-3,2)

• (-3,-2)

• (-2,3)

• (2,-3)
