Answer:
the answer is 1
Step-by-step explanation:
X1=3 X2=7
Y1=-2 Y=r
M=y2-Y1/X2-X1
3/4=r-(-2)/7-3
3/4=r+2/4
Cross multiply
4(r+2)=4*3
4r+8=12
collect like terms
4r=12-8
4r=4
divide the by the co efficient of x
r=1
8 pots
34
first of all use formula:
n(AUB)=n(A)+n(B)-n(AnB)
1/6
Because because there are six books in total and she only red 5 in the way
