It looks like you've uploaded an image showing a coordinate plane with a polygon drawn using specific points. Let's solve the problem step by step and explain what's going on.
Task: Drawing Polygons in the Coordinate Plane
The image shows a coordinate grid with four labeled points:
- (9, 6)
- (7, 2)
- (4, 2)
- (2, 6)
These points are connected to form a
quadrilateral (a four-sided polygon).

Step-by-Step Analysis
Let’s examine each point and how they are connected:
1.
Point A: (2, 6) — located 2 units right and 6 units up
2.
Point B: (4, 2) — 4 units right, 2 units up
3.
Point C: (7, 2) — 7 units right, 2 units up
4.
Point D: (9, 6) — 9 units right, 6 units up
From the diagram:
- The points are connected in order:
(2,6) → (4,2) → (7,2) → (9,6) → back to (2,6)
This forms a
closed shape, specifically a
trapezoid.

Why is it a Trapezoid?
A trapezoid has
one pair of parallel sides.
Let’s check the slopes of the sides:
#### Side 1: From (2,6) to (4,2)
Slope = (2 - 6)/(4 - 2) = (-4)/2 =
-2
#### Side 2: From (4,2) to (7,2)
Slope = (2 - 2)/(7 - 4) = 0/3 =
0 → horizontal line
#### Side 3: From (7,2) to (9,6)
Slope = (6 - 2)/(9 - 7) = 4/2 =
2
#### Side 4: From (9,6) to (2,6)
Slope = (6 - 6)/(2 - 9) = 0/(-7) =
0 → horizontal line
So:
- Side from (4,2) to (7,2): horizontal
- Side from (9,6) to (2,6): horizontal
✔ These two
top and bottom sides are
parallel (both have slope 0), so this confirms it's a
trapezoid.
Also, notice:
- The top side is from (2,6) to (9,6) — length = 9 - 2 =
7 units
- The bottom side is from (4,2) to (7,2) — length = 7 - 4 =
3 units
So it's a
trapezoid with parallel bases of 7 and 3 units, and non-parallel legs.

Conclusion
The polygon formed by connecting the points:
(2,6), (4,2), (7,2), (9,6)
is a
trapezoid.

✔ Final Answer:
The figure is a
trapezoid because it has one pair of parallel sides (the top and bottom sides are both horizontal). The vertices are plotted correctly on the coordinate plane as shown.
If the task was to
identify the polygon, then the answer is:
>
Trapezoid
