Suppose $f$ is a linear function of $x$ . The slope is 2.24. An increase of 6 units in $x$ causes what change in $f$ ?
A) A decrease of 13.44 units
B) An increase of 13.44 units
C) An increase of 2.68 units
D) A decrease of 2.68 units

Quizplus · Accepted Answer

A linear function has a constant slope. Here, the slope is given as 2.24, which means that for every increase of 1 unit in $x$, there will be an increase of 2.24 units in $f$. Therefore, for an increase of 6 units in $x$, there will be an increase of $6 \times 2.24 = 13.44$ units in $f$. So, the answer is option B.
