Answer: Their equations have different y-intercept but the same slope

Explanation:

Since, the slope of the line passes through the points (2002,p) and (2011,q) is,


m_1 = (q-p)/(2011-2002) = (q-p)/(9)

Similarly, the slope of the line asses through the points (2,p) and (11,q) is,


m_2 = (q-p)/(11-2) = (q-p)/(9)

Since,
m_1 = m_2

Hence, both line have the same slope.

Now, the equation of the line one having slope
m_1 and passes through the point (2002,p) is,


y - p = (q-p)/(9)(x-2002)

Put x = 0 in the above equation,

We get,
y = (2000(p-q))/(9)+p

The y-intercept of the line one is
(0, (2000(p-q))/(9)+p)

Also, the equation of second line having slope
m_2 and passes through the point (2,p)


y-p=(q-p)/(9)(x-2)

Put x = 0 in the above equation,

We get,
y = (2(p-q))/(9)+p

The y-intercept of the line one is
(0, (2(p-q))/(9)+p)

Thus, both line have the different y-intercepts.

⇒ Third option is correct.
