19)A)Point A is located in quadrant 1. B)The coordinates are (5,-3), quadrant 2. C) (-5,-3) in quadrant 3.
20) A tessellation is created when a shape is repeated over and over again covering a plane without leaving any gaps or overlaps. Tessellation is also known as tiling. Triangles, squares, and hexagons are perfect examples of figures that can create tessellation. So the figure above can not tessellated a plane because there will be gaps.
21)First I would reflect the figure 1 across the x-axis. Then I would translate the figure 1 and it’s reflection and rotate them 90 degrees.
22)In 2 quadrant and 4 quadrant must lie. I know that in the 1 quadrant, the x-coordinate and the y-coordinate are both positive. In the 2 quadrant, the x-coordinate is negative and the y-coordinate is positive. In the 3 quadrant, the x-coordinate and the y-coordinate are both negative. In the 4 quadrant, the x-coordinate is positive and the y-coordinate is negative. If the coordinate of an ordered pair have opposite signs, then the ordered pair must lie in the 2 quadrant or in the 4 quadrant.
Those answers are 100% percent correct. DON’T USE THE OTHER PEOPLES ANSWERS, THEY ARE NOT CORRECT.

ESSAY WRITE IN YOUR OWN WORDS!! (These have not been graded yet, they could be incorrect)
19)
A) Quadrant I
B) A(4,2) —> A(5,-3) Quadrant IV
C) A(4,2) —> A(-4,2) Quadrant II
20) No you cannot, (explain what a tessellation is and why the shape doesn’t fit)
21) You must rotate the shaded triangle 270 degrees about its vertex to fully shade in the circle. This is because 360/4 is 90 degrees and 90x3 is 270. 4 is the number of positions the shape matches itself in.
22) Because ordered pairs in quadrant I are both positive, and ordered pairs in quadrant III are both negative. This means that the ordered pair is either in quadrants II or IV.
REMEMBER. This should only be used to check your answers. When it comes to state tests you won’t have a way to cheat. Make sure you change the wording of the essay questions so you don’t get caught! Hope this helped!

The length of the bottom side of the rectangle is 9 - 4 = 5 units, since the x-coordinates of the two points are 4 and 9.
The height of the rectangle can be found by calculating the distance between the other two known points:
height = 10 - 5 = 5 units.
Therefore, the coordinates of the fourth vertex can be found by moving 5 units to the left from the first given point (4, 5) and 5 units down from the third given point (9, 5).
The fourth vertex has coordinates:
(4, 0).

a) Point A(4,2) is located in Quadrant I since both coordinates are positive.
b) The translation rule (x,y)-->(x+1,y-5) adds 1 to the x-coordinate and subtracts 5 from the y-coordinate. Applying this rule to point A(4,2), we get:
A'(5,-3)
The translated point A' is located in Quadrant IV since the x-coordinate is positive and the y-coordinate is negative.
c) Reflecting a point across the y-axis negates the x-coordinate and keeps the y-coordinate the same. Thus, the coordinates of the reflected point A" are:
A"(-5,2)
The reflected point A" is located in Quadrant II since the x-coordinate is negative and the y-coordinate is positive.
The line graphed below shows the rate at which a machine can package pieces of candy.
