Another way to look at this problem is the measure of angle made made by the line with x-axis. Clearly the line k makes larger angle with x-axis than line l which refers to more steepness for line k than for line l. So, the answer choice is [A]

Yes, that's right! Just keep in mind that, if we're looking at the angle made below the x axis, and a line makes an angle that's greater than 90 degrees (with the x axis), the slope of that line is negative.

If thr slopes were -ve then how to distinguish which slope is greater than thr other ?

Hi Simardeep,

The slope of a line describes the line's steepness and direction. If we were to take the absolute value of a slope, we would be left with the magnitude of the slope, which only describes the steepness of the line. And if we wanted to compare two lines, the line with a slope of greater magnitude would be the steeper of the two lines.

Hope this helps! :)
