(-2,15)(9,-18)
slope = (-18 - 15) / (9 - (-2) = -33/11 = -3
There can be 2 answers to this question....
point slope form : y - y1 = m(x - x1)
(1) using points (-2,15)...
y - 15 = -3(x + 2) <== one possible answer
(2) using points (9,-18)
y + 18 = -3(x - 9) <== another possible answer
Answer:
6 times
Step-by-step explanation:
1. There was no cents left
2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)
3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)
4. It equals 6 and 6 is a even number
5. Sorry this was too confusing
Answer: 33 degrees

Angles inscribed in the same arc are congruent, so
Answer:
Q1: dot plot
Q2: box plot
Q3: box plot
Step-by-step explanation:
Question 1 is the dot plot because there is a dot for each playlist. 14 has no dots. Its not the box plot because its doesnt tell you how many times a certain number of playlists appears on the number line, it only gives the ranges of the quartiles and the median.
Question 2 is the box plot because the line that splits the two rectangles is always the median. Therefore the box plot tells you that the median is 13. Its not the dot plot because youd have to pine up all the dots and find the one middle in the middle which takes much longer
Question 3 is the box plot because the interquartile range is the biggest rectangle (from 7 to 15 on the number line). If you find it hard to remember what the interquartile range is, the question will gives clues as to what to look for. In this question it tells you that the interquartile range is 8. We know that range means the gap beweet 2 numbers so just try and find a difference of 8 between 2 of the outlined numbers. Also interquartile sounds like inner quarter so that can help with remembering where it is. Its not the dot plot because its just too simple to quickly find something like the interquartile range.
Remember that the question is only asking which plot makes finding something easier. if you can find what theyre talking about more easily on one of the plots then thats probably the answer.
Hope this helps :)
