Answer:
Sweetie, it's easy. Let me explain. 
The slope formula is (y2 - y1) (x2 - x1) you find the slope by putting the rise over the run. For example, if the point goes up 2 and right 3 your slope would be (2,3) and let's just say your next coordinate is (4,5) you would take the y, 5, from the second coordinate and subtract it by the y from the first coordinate, 3. So you would have 2 and you do the same with the x values. So your slope would be 3/2. Hope I helped at all.

Let's say Bailey takes "b" days to paint it.
and Andrew takes "a" days to paint the same house.
now, Andrew is 6 times faster than Bailey, therefore, if Andrew takes "a" days to do it, Bailey takes then "6a" days, or b = 6a.
now, the year they worked together, they finished it in 7 days.
so, after 1 day then, they have only done 1/7 of the whole work.
and Andrew for one day, has done 1/a of the house, whilst Bailey has done 1/b of the house or 1/(6a).

Here are some probability scenarios.
- Flipping a coin and seeing if it is heads or tails.
- Thinking to yourself:  "Is it going to rain or hail?"
- Spinning a spinner and seeing what color it lands on.
-  Probability in winning the lottery.
-  Having 5 pairs of black shoes and one pair of yellow shoes.
  The probability of picking the yellow shoe is 1/5.
There are lots of more examples out there!
