In the xy plane, line x goes through the point (a,1) and line y goes through the point (1,b). If the lines x and y intersect, is the slope of x bigger than the slope of y?
(1) a > b
(2) |a| > |b|
From F.S 1, Assume a=1,b=0.
From the graph,line y is represented as blue and has a slope of 0.Thus, For the green line,which passes through (1,1), the slope is negative and thus less than the slope of line y
For the red line, which passes through (1,1), the slope is positive and more than the slope of line y.Insufficient.
From F.S 2, assuming the same set as a=1,b=0, we have the same result as above.
Taking both together , we have nothing new to add.
