Answer:
perpendicular slope = - 
Step-by-step explanation:
given a line with slope m then the slope of a line perpendicular to it is
= - 
the given slope m = 4, hence
= -
The simplified probability would be 12/91.
There are 4 green jelly beans out of a total of 14 jelly beans. The probability for the first bean would be 4/14.
Once the first jelly bean is removed, the probability that the second jelly bean would be red is 6/13 (the denominator decreases by 1 because of the first jelly bean that did not get put back).
Together the probability is (4/14)(6/13) = 24/182, which then simplifies to 12/91.
The slope of line PQ is m1 = ( 3 - (-3) ) / (2 - (-2) ); then m1 = 6/4 = 3/2;
In the same way, the slope of line RS is m2 = -7/5;
But (3/2) x (-7/5) = -21/10, which is diferrent from - 1;
So, the lines aren't perpendicular.
