Question 1161242: If two lines l and m have equations y = -x + 6, and y = -4x + 6, 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.

I have tried doing the area of success over possible and I know the possible is 81 because 9*9. I can't figure out the rest. please help

In this problem, the probability is the ratio (a fraction), where the numerator is the difference of the areas of the two triangles,

while the denominator is the larger area of the two right-angled triangles.
