Exploring Proportional and Nonproportional Relationships

What is the general form of a proportional equation?

• y = KX

• y = MX

• y = X + B

• y = MX + B

In a non-proportional equation, what does 'B' represent?

• The slope

• The y-intercept

• The x-intercept

• The constant of proportionality

How can you identify a proportional graph?

• It is a horizontal line

• It is a straight line that does not pass through the origin

• It is a curved line

• It is a straight line that passes through the origin

What is the key difference between proportional and non-proportional graphs?

• Proportional graphs pass through the origin, non-proportional graphs do not

• Non-proportional graphs are horizontal

• Proportional graphs are curved

• Non-proportional graphs pass through the origin, proportional graphs do not

In a table, how can you determine if the relationship is proportional?

• The ratio of y to x is constant

• The sum of y and x is constant

• All x-values are the same

• All y-values are the same

What does it mean if a table has a constant ratio of y to x?

• The relationship is non-proportional

• The x-intercept is zero

• The y-intercept is zero

• The relationship is proportional

How do you write the equation of a non-proportional relationship from a table?

• y = MX + B

• y = KX

• y = MX

• y = X + B

What is the y-intercept in the equation y = MX + B?

• B

• X

• M

• Y

Which of the following is true for non-proportional equations?

• They have a y-intercept other than zero

• They always pass through the origin

• They have a constant ratio of y to x

• They are always horizontal lines

What is the main characteristic of proportional equations?

• They have a y-intercept other than zero

• They are always horizontal lines

• They pass through the origin

• They have a variable slope
