If the image of the line y = 3x + P intersects the X axis of the line y = - 2 + Q at the same point, then the relation between P and Q is——————
The intersection of the line y = 3x + P and the X axis is:
Substituting y = 0, we get x = - P / 3
That is: the intersection of the line y = 3x + P and the X axis is (- P / 3,0)
This point is also on the straight line y = - 2x + Q. substituting it, we get:
0=-(2p/3)+q
3q-2p = 0
