Question

what is the contrapositive of the conditional statement? if two variables are directly proportional, then their graph is a linear function. if two variables are directly proportional, then their graph is not a linear function. if the graph of two variables is a linear function, then the two variables are directly proportional. if the graph of two variables is not a linear function, then the two variables are not directly proportional. if two variables are not directly proportional, then their graph is not a linear function.

Explanation:

The contrapositive of a conditional statement "If p, then q" is "If not q, then not p". Here, p is "two variables are directly proportional" and q is "their graph is a linear function". So the contrapositive is formed by negating both p and q and reversing them.

Answer:

If the graph of two variables is not a linear function, then the two variables are not directly proportional.
