Answer:
Step-by-step explanation:
A. BECAUSE THERE IS 2 BARS WITH NUMBER OF STUDENTS AS 4
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal. A line parallel to
, will have the same slope -3. Thus, the equation will be of the form:

We substitute the given point and find "b":

Finally, the equation is:
