The straight line y-2x-6=0 cuts the x-axis and the y-axis at the point A and B respectively.A fixed point C is such that the gradient of the straight line BC is 1/2 and the straight line AC is perpendicular to the straight line CB.Find the coordinate of point A and point B ,the equation of the straight line BC ,the equation of the straight line AC ,the coordinates of point C ,the area of the triangle ABC.pls help me thanks.....



Y - 2x - 6 = 0

apabila memotong paksi-x
∴ A ( -3,0)

apabila memotong paksi-y
x=0, y=2x+6
         = 2(0)+6

p/s:ayat selepas tu, saya tak faham
