The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
<h3>What is the statement about?</h3>
To known a statement that is contrapositive, you will need to negate the hypothesis as well as the conclusion of the statement, and also switch their positions.
Hence:
- If two variables are directly proportional, so their graph is a linear function.
- If two variables are not directly proportional, so their graph is not a linear function.
Therefore, The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
