Problem

A point is

\dfrac{5}{2}

units left of the

y

-axis and

\dfrac{7}{4}

units below the

x

-axis. Which ordered pair represents this point? a)

\left(\dfrac{5}{2},\dfrac{7}{4}\right)

\left(\dfrac{5}{2},-\dfrac{7}{4}\right)

\left(-\dfrac{5}{2},-\dfrac{7}{4}\right)

\left(-\dfrac{7}{4},-\dfrac{5}{2}\right)

Intuitive explanation

The key is translating "left" and "below" into signed coordinates. Left of the $y$ -axis means negative $x$ -value, and below the $x$ -axis means negative $y$ -value. Just match the distances to their directions and you'll have your ordered pair $(x, y)$ .
