Polygons are closed figures so any figure that is not closed is not a polygon
Well <span>(x, y)→(−x, y) </span>means it's reflected off the y-axis(You can experiment this with random points on a graph)
(x, y)→(x−1, y+2) means that every point is moved to the left by 1 and up by 2, in other words, the triangle is translated left 1 up 2.
Since the only thing that effects congruency is dilation(rotation, translation, and reflection only move the shape, not change it), The new triangle should equal the old one.
Thus we would get the first choice
2000 mL= 2 L
Hope this helps

Answer: The slope is
Step-by-step explanation:
The following formula is used to find the slope of a line:
You know that that line passes through these points:
Then you can identify that:
Knowing these values you can substiute them into the formula and evaluate, in order to find the slope of this line.
This is:
1 3/4 × 4 = 7/4 × 4 = 7 hours on saturdays
3/4 × 3 = 9/4 = 2 1/4 hours on Wednesdays
7 + 2 1/4 = 9 1/4 hours of volunteering total
