All you need for a point to be left unchanged is it being on the line of reflection. (Generally speaking)
The first one is wrong cause you can have a line of reflection anywhere. If the line is horizontal ( x axis) then the slope would be zero. Whereas a line on y axis would be an undefined slope. There are also diagonal lines of reflections which have slopes
I am pretty sure the second one would be correct because, as previously stated, all the line needs to stay in the same place is it being on the line of reflection.
Again, lines of reflection do not have a set slope, a diagonal line of reflection going like / on the chart through the axis could have a slope of one, but it is not needed for the point to remain in the same place
The point does not necessarily need to be on the origin, it can be anywhere on the line of reflection, and if the line of reflection does not pass through the origin, a point on the origin would be moved in a reflection.
I hope this makes sense and helps you out a bit... have a good day

Answer:
-3/12
Step-by-step explanation:
In negative numbers, it's basically the opposite of regular numbers.
Let's explain negative numbers as debts. Let's say you owe a friend 1 dollar, and another 2 dollars. In a sense, you'll have -1 dollars, and -2 dollars. Which one is the greater number? It'll be -1 as you're only losing 1 dollar. Same goes here. Although 1 is a greater number than 3/12, in negative form it isn't.
Answer:
Step-by-step explanation:
.
a. Yolanda only wins if the cup lands upright.
From the experimental data we see that the probability of winning is 5 out of 50, or
10%. Therefore, if Yolanda plays 10 times she can expect to win 10% of 10 times = 1
time. She will lose 9 times. (Note: Ten trials is a very small number of trials, so we should not be surprised if Yolanda’s results are very different from the percentages
produced by the longer experiment.)
b. If Yolanda wins 1 time and plays 10 times, she will have spent $10 to play and won
back only $5, so she would have less money at the end of 10 games.
