2. If the straight line Y=2X+M does not pass through the second quadrant, then the value range of the real number m is (m≤0).
3. The image with y = (-32/3) x is a straight line passing through the origin and point (-3,32).
4. If the image of linear function Y=KX+B passes through two points, namely point P (1, 0) and point Q (0, 1), then K=(-1) and B=( 1).
5. The straight line passing through point (0,2) and parallel to the straight line Y=-X is (y=-x+2).
6. The linear function Y= 1/2X+2 is known. When X(=-4), Y = 0；; When x (>-4) and y > 0.
7. If the image of the linear function Y 1=KX-B passes through the first, third and fourth quadrants, the image of the linear function Y2=BX+K passes through the (1, 2,3) quadrant.
