Point slope is y-y1=m(x-x1) where m is slope and x1 and y1 are the given x and y values.
y-(-1)=-3(x-7)
y+1=-3(x-7)

Correct option is D.
Answer:
A, B, C
Step-by-step explanation:
x is in the intersection of sets B and C, in set B, in set C, in the union of sets B and C, in the union of sets A and C
Answer: A, B, C
Answer:
x^2-10x+25
Step-by-step explanation:
(a+b)^2=a^2+2ab+b^2 so a=x and b=-5 so the expression is x^2-10x+25
This is what we already know:
![\left[\begin{array}{cccc} &YB&NB&total\\YF&45&[unknown]&146\\NF&[unknown]&[unknown]&[unknown]\\total&144&[unknown]&428\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D%20%26YB%26NB%26total%5C%5CYF%2645%26%5Bunknown%5D%26146%5C%5CNF%26%5Bunknown%5D%26%5Bunknown%5D%26%5Bunknown%5D%5C%5Ctotal%26144%26%5Bunknown%5D%26428%5Cend%7Barray%7D%5Cright%5D%20%20%20)
And using this information, we can fill the table out. Remember that everything must add up to the total in the column and row. The complete table looks like this:
![\left[\begin{array}{cccc} &YB&NB&total\\YF&45&101&146\\NF&99&183&282\\total&144&284&428\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D%20%26YB%26NB%26total%5C%5CYF%2645%26101%26146%5C%5CNF%2699%26183%26282%5C%5Ctotal%26144%26284%26428%5Cend%7Barray%7D%5Cright%5D%20)
Using the complete table, we see the fraction for students that only like baseball is 
and students who only like football is 
. All you need to do is add these fractions together to get your answer.
In short, 200 students only like one of the two sports.
