The equation of the line through the points (4,2) and (-8, -2) is 3y = px + q, where p and q are constants. Find the value of p.

A.

B.

2

C.

3

D.

9

Correct answer is A

Using the two - point from

yy1y2y1=xx1x2x1

y222=x484

y24=x412

12(y2)4 = x - 4

3(y -2) = x -4

3y - 6 = x - 4

3y = x - 4 + 6

3y = x + 2...

By comparing the equations;

3y = px + , p = 1
