If two lines l and m have equations y = -x + 8, and y = -4x + 8, what is the probability that a point randomly selected in the 1st quadrant and below l will fall between l and m? Express your answer as a decimal to the nearest hundredth.

First....you should graph the two lines.....here is a graph :   https://www.desmos.com/calculator/xqbnu0g6mt

   now calculate the area of the larger triangle    ( remember area = 1/2 b h )

     and calculate the area of the smaller triangle

      prob  =  (larger - smaller) / larger
