Choice A is wrong since it does not exclude the case in which a and b are equal so that the line has a slope of 1. Choice C is right because it assures that the slope is greater than 1 without the risk of equality.
The one I do not get is choice B. If line m is perpendicular to n and it has a slope of 1, this means that line n has a slope of 1 that is not greater than 1. How could it be right?

Got it. I was too tired yesterday to get it right! Thanks!

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?

Could you please explain further? That's a rule ; The slope of line n is always equal the negative reciprocal of perpendicular line m

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.

@Avraheem, the question asks which of the options individually will help you determine if the slope of n will be greater than 1.
Options b and c give you concrete values  option B  slope is 1  helps you determine if the line's slope is above 1, in this case it's not. Option C leads you towards a negative slope, which results in helping you decide if the slope is above 1  nope.
Option A on the other hand, just tells you that the line doesn't pass through a point a,b where a>b and a and b are both positive. It could pass through any other points such that the slope will be positive or negative or 0. We can't use that particular information to decide whether the slope of line is above 1 or not. Hence B & C.

I think the choice c is missing a data it should say c and d are positive otherwise if you take c and d negative slope becomes 1 and if you take c and d positive slope is over 1
