Cotx = Cosx/sinx
1/Cotx = sinx/cosx
Sinx + cosx *1/cotx = sinx + cosx * sinx/cosx = 2sinx
The slope of a line usually determines id the line is negative or positive. For example, lines going uphill, or uphill slopes, are positive slopes. The slope will be a positive number such as, yet not limited to, 5, 10, or 57. Or you can also take their counter parts for example, downhill slopes would be considered negative slopes, meaning they go below zero, instead of above, like positive slopes. Hope this helps. :D
