How to use the slope formula to find the slope of a line<br> please help me!!!!!!!
stepan [7]

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.

Andrew
PilotLPTM [1.2K]
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).

\bf \stackrel{\textit{Andrew's rate}}{\cfrac{1}{a}}+\stackrel{\textit{Bailey's rate}}{\cfrac{1}{b}}=\stackrel{\textit{1 day of work}}{\cfrac{1}{7}}&#10;\\\\\\&#10;\cfrac{1}{a}+\cfrac{1}{6a}=\cfrac{1}{7}\impliedby &#10;\begin{array}{llll}&#10;\textit{let's multiply all by }\stackrel{LCD}{42a}\textit{ to toss the}\\&#10;denominators&#10;\end{array}

\bf 42a\left( \cfrac{1}{a}+\cfrac{1}{6a} \right)=42a\left( \cfrac{1}{7} \right)\implies 42+7=6a\implies \cfrac{49}{6}=a&#10;\\\\\\&#10;\stackrel{days}{8\frac{1}{6}}=a&#10;\\\\\\&#10;\textit{how many days will it take Bailey then?}\quad b=6a&#10;\\\\\\&#10;b=6\cdot \cfrac{49}{6}\implies b=\stackrel{days}{49}

Probability scenarios?
velikii [3]

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!
