Answer:
B. is the answer
Step-by-step explanation:
y>-3x+2
let's do one by one
A. Is 2>-3(-4)+2? negative times negative is positive so 2 is not greater than 12 +2 or 14
B. is 2>-3(4)+2? -3•4=-12 +2 =-10 so yes 2>-10
C. is -2>-3(-2)+2? negative •negative is positive 6+2=8 so -2 is not greater than 8
D. is 0>-3(-4)+2? -•-=+ so 12+2=14. so 0 is not greater than 14
The answer is 3/4..............
That would be DF is congruent to DE ( first choice)
( they are both = sqrt(2^2 + 3^2)
