In page 217 of the second edition of geometry, i.e in the hard practice question no. 19, I am having a confusion.
Q In the x-y plane, line n is a line that passes through the origin. Which of the following statements individually provide(s) sufficient information to determine whether the slope of line n is greater than 1? Indicate all such statements
a) Line n does not pass through any point (a,b) where a and b are positive and a>b
b) Line m is perpendicular to n and has a slope of -1
c)Line n passes through the point (c, d+1) where c and d are consecutive integers and c>d
In the solution, it is given B and C are correct. But both these options point out the fact that the slope of the line is 1, not greater than 1, which is required as per question! Please give your opinion on this and give me a solution.
