Hi. I am confused when do we consider a slope to be negative? I mean, when both slopes are negative then how to decide which one is greater slope?

@Pratishtha12345 Hello all,I know its an old post still I am sharing the answer so that its helpful to others: 1) Slope of a line is considered to be positive, if a point on the line moving from left to right, travels upwards. 2) slope of line is considered to be negative, if a point on the line moving from left to right, travel downwards.3) To find the line having greatest slope is the one, which has the greatest absolute value for the slope. Hope its clear and if any doubts please ask. .....Regards

 A box contains three pairs of blue gloves and two pairs of green gloves. Each pair consists of a left-hand glove and a right-hand glove. Each of the gloves is separate from its mate and thoroughly mixed together with the others in the box. If three gloves are randomly selected from the box, what is the probability that a matched set (i.e., a left- and right-hand glove of the same color) will be among the three gloves selected?
