Answer: B. neither perpendicular nor parallel
Step-by-step explanation: If the lines were perpendicular, the coefficients would be swapped and one negated. (You would have 8x -y = c, or 9x +2y = c in the system.)
If the lines were parallel, the coefficients in the two equations would only differ by a common factor. (Both equations would reduce to 2x -9y = c, or x +8y = c.)
The lines are not the same line (coefficients are different).
So, the only reasonable description is ...
neither perpendicular nor parallel

Answer:
6417
Step-by-step explanation:
if A = b*h then when we substitute b for 93 and h for 69
A=93*69 = 6417
