Answer:
3/13
Step-by-step explanation:
There are 12 face cards in a deck of 52 cards. The fraction is 12/52 and you simplify so the answer is 3/13. (about 23 percent and face cards are kings, queens and jacks)
set y = kx+b
for (4,-2): -2=4k+b (function 1)
for (-1,8): 8=-k+b (function 2)
Use function 2 subtract function 1:
10=-5k
k=-2
SO the slope is -2.
