2
Step-by-step explanation:
Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:

Plug in the values



Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
2)
a*2 + b = 26;
a*(-4) + b = -16;
then, a*6 = 42 => a = 7 => b = 26 -14 => b = 12;
from table, 7*9 + 12 = 63 + 12 = 75, correct;
7*(-8) + 12 = -56 + 12 = -44, correct;
slope = ( -44 + 16) / ( -8 + 4) = ( - 28) / (-4) = 7 = a;
