What is the constant of proportionality?

• It is the x-axis on a graph.

• It is the same as the unit rate.

When graphing a relationship on the coordinate grid ... The line is straight and it passes through the origin, therefore we have a ______________.

• Proportion

How can you use the unit rate to create an equation for a relationship? (Remember the unit rate is the same as the constant of proportionality)

• y=abc+def+ghi

• y=5$3

• y=constant of proportionality(x)

• y=305x + 88 -4 abc

When graphing a relationship that is in a table, the relationship is proportional if, and only if, (select TWO)

• The line is curvy and pretty.

• The line is straight.

• The line passes through the origin.

• The line does not pass through the origin.
