Graphing Proportional Relationships

Can a proportional relationship be represented by a table?

• Yes, a proportional relationship can be represented by a table where the ratios of y to x are constant.

• No, a proportional relationship cannot be represented by a table.

• Yes, but only if the values are whole numbers.

• No, it can only be represented by a graph.

Is this graph proportional? (It passes through the origin and is a single straight line)

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

• No, it does not pass through the origin

• Yes, but it is not a straight line

• No, it is a curved line

What is the formula for a proportional relationship?

• y = kx, where k is the constant of proportionality.

• y = k + x, where k is a constant.

• y = k/x, where k is a constant.

• y = k^2, where k is a constant.

If a graph shows a straight line but does not pass through the origin, what can you conclude?

• It is a proportional relationship.

• It is not a proportional relationship.

• It represents a quadratic function.

• It has a negative slope.

What is the y-intercept of a proportional relationship?

• The y-intercept is always 0 in a proportional relationship.

• The y-intercept can be any positive number.

• The y-intercept is always equal to the slope.

• The y-intercept is undefined in a proportional relationship.

What does it mean for a relationship to be proportional?

• A proportional relationship means that two quantities increase or decrease at the same rate.

• A proportional relationship means that one quantity is always greater than the other.

• A proportional relationship means that the two quantities are unrelated.

• A proportional relationship means that the two quantities can only increase together.

What happens to the graph of a proportional relationship if the constant of proportionality increases?

• The line becomes steeper as the constant of proportionality increases.

• The line becomes flatter as the constant of proportionality increases.

• The line shifts to the left on the graph.

• The line remains unchanged regardless of the constant of proportionality.
