Question

the points $p(2, -3)$, $q(1, 5)$, $r(-6, 9)$, and $s(-5, 1)$ form quadrilateral $pqrs$. plot the points then click the \graph quadrilateral\ button.
click on the graph to plot a point. click a point to delete it.

Explanation:

Step1: Plot point P

Locate $x=2$ on the horizontal axis, $y=-3$ on the vertical axis, mark the intersection point $P(2, -3)$.

Step2: Plot point Q

Locate $x=1$ on the horizontal axis, $y=5$ on the vertical axis, mark the intersection point $Q(1, 5)$.

Step3: Plot point R

Locate $x=-6$ on the horizontal axis, $y=9$ on the vertical axis, mark the intersection point $R(-6, 9)$.

Step4: Plot point S

Locate $x=-5$ on the horizontal axis, $y=1$ on the vertical axis, mark the intersection point $S(-5, 1)$.

Step5: Connect the points

Draw line segments $PQ$, $QR$, $RS$, $SP$ in order to form quadrilateral $PQRS$.

Answer:

The quadrilateral PQRS is formed by plotting the points $P(2, -3)$, $Q(1, 5)$, $R(-6, 9)$, $S(-5, 1)$ and connecting them in sequence.
