Slope Formula: m= \frac{ y_{2} }{ x_{2} }  -  \frac{ y_{1} }{ x_{1} }

I am going to show you how to do this on problem 6, and you will do the rest of the problems. 

Here are the steps to solving problem 6

Step 1) Substitute the coordinates into the slope formula

\frac{-1-2}{-18-(-8)}

Step 2) Now Lets simplify the denominator, so we don't have two Subtractions symbols.

\frac{-1-2}{-18+8}

Step 3) Simplify

\frac{-1-2}{-18+8} =  \frac{-3}{-10}

Step 4) We can still simplify more

\frac{-3}{-10} =  \frac{3}{10}

Hope This Helps ... Good Luck

[The reason I didn't do all of them is because you need to know how to do them. Trust me later on knowing these is going to be very handy.]

7.5% of the box office reciepts on a friday night are $270. What are the total box office reciepts
MrMuchimi
Hello there! To solve for the total box office receipts, we can write and solve a proportion. Set it up like this:

270/x = 7.5/100

We do that, because we are looking for the total and 270 is the part of the whole. 270 makes up 7.5% of the box office receipts. 
Now, we cross multiply. 270 * 100 is 27,000. 7.5 * x is 7.5x. Divideeach side by 7.5 to isolate the "x". 7.5x/7.5 cancels out the "x". 27,000/7.5 is 3,600. There. x = 3,600. The total box office receipts are $3,600.

How many distinct seven-digit phone numbers can you create from the numbers 4, 4, 5, 6, 7, 7, 7? (e.g. 445-6777 is one example)?
iris [78.8K]
You have 7 numbers, two numbers 4 , one 5, one 6 and three numbers 7.

From these 7 numbers you can create 7!=1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot7=5040 phone numbers, but they are not all different.

If you have two numbers 4, then you have to divide obtained number by 2! (the number of all possible permutations of two numbers 4) and since you have three numbers 7 you should divide the obtained number by 3! (<span>the number of all possible <span>permutations of three numbers 7</span>). Then</span><span /><span>
</span><span>
</span><span>\dfrac{5040}{2!\cdot 3!}= \dfrac{5040}{1\cdot2\cdot1\cdot2\cdot3}=420.</span>

Answer: You can create 420 different phone numbers.<span />
