Which function is even? check all that apply a. y = csc x
b. y = sin x
c. y = sec x
d. y = cos x

c and d

Step-by-step explanation: they’re both even

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
