Dan either walks or cycles to school.
the probability that he cycles to school is
(a) write down the probability that dan walks to school.

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
