answer to nov 2009 q18
iluvme solved this question, but she was too lazy to post it!!
ans- find the co-ordinates of point A, taking Y=0, use the line quation to help you
point Y=2x + 8
0 - 8 = 2x
x=-4
Point A= (-4,0)
distance between A and B is 9 units
A to origin is 4 units, so point B is at (5,0)
use point b C0-ordinates to find C
Y=2x+c
0=2(5) + c
c= -10
Hope She helped
