If these two lines are parallel, they would have the same gradient.
Since Gradient = Rise / Run,
8 / -12 : -4 / 1
These two ratios are obviously not the same, so we can conclude the lines are not parallel.
Answer: For your specific problem, h = 300 / (4 + 5 + 6) = 300 / 15 = 20
Step-by-step explanation:
I think that your answer would be B) lines that meet at a 90 degree angle. These lines must intersect, and they have slopes that are opposite reciprocals when compared to each other.
