Answer:
A.
C.
Step-by-step explanation:
Given:
The given line is
Express this in slope-intercept form , where m is the slope and b is the y-intercept.
Therefore, the slope of the line is .
Now, for perpendicular lines, the product of their slopes is equal to -1.
Let us find the slopes of each lines.
Option A:
On comparing with the slope-intercept form, we get slope as .
Now, . So, option A is perpendicular to the given line.
Option B:
For lines of the form , where, a is a constant, the slope is undefined. So, option B is incorrect.
Option C:
On comparing with the slope-point form, we get slope as .
Now, . So, option C is perpendicular to the given line.
Option D:
On comparing with the slope-intercept form, we get slope as .
Now, . So, option D is not perpendicular to the given line.

My answer:
C and Y are not independent events because P(C∣Y) ≠ P(C).
Probability of C = 110/300 = 0.37
Probability of Y = 75/300 = 0.25
Probability of (C|Y) = 0.37 * 0.25 = 0.0925
As you can see, </span><span>P(C∣Y) is 0.0925 which is not equal to P(C) = 0.37. Thus, C and Y are not independent events. </span><span>
