Parallel line means the same slope
（8-1）/(-17-a)=(1-5)/(a+2)
so a is 18

Answer:
Step-by-step explanation: Formula to find an area of a triangle A= 1/2base x height
Data
h=12mm A=1/2 base x height
b=14mm. A= 1/2 x (14mm x 12mm)
A=? A= 168mm^2(square) /2
A= 84mm square
It appears that for every question missed, it deducts 3 points.
so if Julie missed 6 questions, then she received a : (-3 * 6) = -18
