Lines n and p lie in the xy-plane. Is the slope of line n less than the slope of line p?
(1) Line n and p intersect at point (5,1)
(2) The y intercept of line n is greater than the y- intercept of line p

C?
1. alone doesnt give us much info, ie slope.
2. taking 2 alone still does surve the much.
taking both we know the common point, and since y-int of n is greater its slope is always less steepler or more negaive. so C.
What is both the slopes are negative? The one with larger incercept will have a larger slope!
But in case both are positive, the one with smaller intercept will have larger slope.
if both r negative, the one with larger y-int will have a larger negative slope. If a slope is more more negative, wouldn't that make it smaller? I know from a steepness point of view its not true. Please correct me, as I am little unsure. thanks
