Identifying the Constant of Proportionality in Tables and Graphs

What is the first step in identifying the constant of proportionality in a table?

• Multiply the y and x values

• Add the y and x values together

• Divide the y value by the x value

• Subtract the x value from the y value

What does COP stand for?

• Constant of Proportion

• Constant of Proportionality

• Coefficient of Proportionality

• Coefficient of Proportion

What is the next step after creating ratios in the process of finding the COP in a table?

• Subtract the ratios

• Add the ratios together

• Divide to find the COP

• Multiply the ratios

What is the significance of creating ratios in identifying COP?

• To calculate the sum of y and x values

• To establish the equality of the ratios indicating proportionality

• To find the difference between y and x values

• To determine the slope of the line

How do you verify the constant of proportionality in a table?

• By checking if all ratios equal 1

• By comparing the ratios to a standard value

• By confirming all ratios are the same

• By ensuring all ratios are different

What was the COP in the provided table example?

• 47

• 6

• 5

• 50

In the context of graphs, what axis represents the y-value?

• None of the above

• Diagonal

• Vertical

• Horizontal

What was the COP identified in the graph example?

• 47

• 5

• 6

• 50

When is a line considered proportional on a graph?

• When it is a curved line

• When it passes through the point (1,1)

• When it has a negative slope

• When it passes through the point (0,0) and is straight

How can you confirm the COP in a graph?

• By dividing y by x for at least one point and checking if it's consistent

• By calculating the area under the curve

• By ensuring all points form a straight line

• By measuring the distance between points
