If the intersection of their images and the y-axis is divided into two parts, the first-order functions y = (n-4) x + (4-2m) and y = (n + 1) x + M-3 are given The first-order functions y = (n-4) x + (4-2m) and y = (n + 1) x + M-3 are known If the intersection of their image and Y axis is point P and point Q respectively If P and Q are symmetric about X axis, the value of M is______ .

If the intersection of their images and the y-axis is divided into two parts, the first-order functions y = (n-4) x + (4-2m) and y = (n + 1) x + M-3 are given The first-order functions y = (n-4) x + (4-2m) and y = (n + 1) x + M-3 are known If the intersection of their image and Y axis is point P and point Q respectively If P and Q are symmetric about X axis, the value of M is______ .


one
If x = 0, then Y1 = 4-2m; if x = 0, then y2 = m-3
Point P and point q are symmetric about X axis
y1+y2=0
4-2m+m-3=0
m=1



Given that the abscissa of the intersection of two images of a linear function y = 2x + m and y = 3x + 2m is 1, then M=______ .


Substitute x = 1 into y = 2x + m to get y = 2 + m; substitute x = 1 into y = 3x + 2m to get y = 3 + 2m, so 2 + M = 3 + 2m, the solution is m = - 1. So the answer is - 1



When we know the value of the linear function y = (3-K) x-2k * k + 18, the intersection of its image and Y axis is above the X axis


y=(3-k)x-2k^2+18
X = 0, function y = (3-K) x-2k ^ 2 + 18, image and Y axis have intersection
The intersection of the image and the Y axis is above the X axis
y=18-2k^2>0
k^2



Let L kx-y + 1 + 2K = 0 (k belongs to R) (1) if l intersects the negative half axis of x-axis at a, the positive half axis of y-axis at B, and the area of triangle AOB is s, find s


S=2+2k+1/2k
S = bottom multiply height multiply 1 / 2
