I don't really get why the answer choices are B and C? I don't understand why thatyio make B true?
Could you please explain further?
That's a rule ; The slope of line n is always equal the negative reciprocal of perpendicular line m
My problem is in understanding the question! I understand completely why the solutions, but i don't understand the question.
It says which one guarantee that we will have a slope > 1 for line n.
Choice A: is sufficient because we have the case when a = b, and we might as well have slope larger than 1. So it should be true.
Choice B: insures that line n will have a slope of 1, so it should be false too.
Choice C: insure that we will have (c,c), which will always give slope of 1 for line n, so it should be false.
None of them guarantee that we will have slope larger than 1 except A.
