There are 12 colored books of equal size in a bag. 4 of these blocks are blue 5 are green and 3 are red. if a block is removed from the bag at random what is the probability that it will be blue?

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:

option c

the answer should be a. snail
