Last equation (D)

Step-by-step explanation:

Since they want the perpendicular slope, we must take the negative reciprocal if the slope in the equation given. So the negative reciprocal of -1/3 is 3 so that takes out the first and third equation. Now we have to use point slope which is y - y1= m (x - x1) . Doing this gives us y - 5 = 3(x+2) which  is the last equation.

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
