You will flip the signs when you have to multiply or divide your equation by a negative integer.
Answer:
parallelogram
Step-by-step explanation:
slope of DE = (4-7) / (-4 - 2) = 1/2
slope of FT = (-3 - -6) / (11-5) = 1/2
DE // FT
slope of EF = (-6 - 4) / (5 - -4) = - 10/9
slope of DT = (-3 - 7) / (11 - 2) = - 10/9
EF // DT
Since there are 21 questions and one is extra credit, the fraction is 21/20. Divide it to get 1.05. In percent, this is 105%. Hope this helps!
