distribution below?
probability distribution
o

the probability is 1/5 or 25%

Step-by-step explanation:

since the possible answers are 1,2,3,4, or 5, and only one is chosen, there is a 1/5 chance of getting each number.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
