GCSE Maths - What are Reciprocal Graphs? #79

What is the most common form of the equation where Y is equal to something over X?

• y = X

• y = 1/X

• y = X/1

• y = X^2

How can you verify if a graph is y = 1/X?

• By checking if it is a circle

• By ensuring it is a straight line

• By making a table of X and Y values

• By checking if it crosses the Y-axis

What happens to the graph of y = 1/X when X is zero?

• Y becomes zero

• Y becomes infinite

• Y becomes one

• Y becomes negative

How does the graph of y = A/X change when A is greater than one?

• The graph moves away from the axis

• The graph moves closer to the axis

• The graph becomes a straight line

• The graph does not change

What is the effect on the graph of y = A/X when A is negative?

• The graph remains in the same quadrants

• The graph swaps to the top left and bottom right quadrants

• The graph becomes a vertical line

• The graph becomes a horizontal line
