3. If the image of inverse proportional function y =- passes through point (a, -a), the value of a is ().
4. The image of linear function y = 3x+m- 1 does not pass through the second quadrant, so the value range of m is ().
a . m≤ 1 b . m ≤- 1 c . m > 1d . m < 1
5. The schematic diagram of functions y = kx and y = (k ≠ 0) in the same coordinate system is shown in figure 1, in which the correct one is ().
6. Given the linear function y = kx-2 and y decreases with the increase of x, the inverse proportional function y = ().
A. when x > 0 and y > 0.
B in each quadrant, y decreases with the increase of x.
C. the image is in the first and third quadrants.
D. the image is in the second and fourth quadrants.
