The abscissa of the intersection of the lines Y1 = K1X + B1 and y2 = k2x + B2 is a. if K2 > 0 > K1 x > A, then the relationship between Y1 and Y2 is

The abscissa of the intersection of the lines Y1 = K1X + B1 and y2 = k2x + B2 is a. if K2 > 0 > K1 x > A, then the relationship between Y1 and Y2 is

The relationship between Y1 and Y2 is Y2 > Y1
Because K2 > 0 > K1
So Y1 decreases with the increase of X, y2y1 increases with the increase of X
Because x = a is a function with equal values
So when x > A, Y2 > Y1

If two lines Y1 = K1X + B1, y2 = k2x + B2 are symmetric about the Y axis, what are the relations between K1 and K2, B1 and B2

On Y-axis symmetry
When X1 = x2 = 0, Y1 = Y2
y1=b1
y2=b2
So B1 = B2
When y = 0, X1 = - x2
x1=-b1/k1
x2=-b2/k2
Then B1 / K1 = - B2 / K2
And B1 = B2
So K1 = - K2

Given that the intersection of the lines Y1 = k1x-1 and y2 = k2x + 2 is on the X axis, then K1: K2=

1：-2
When the intersection point is on the X axis, i.e. y = 0, X is equal; when Y1 = 0, x = 1 / K1; when y2 = 0, x = - 2 / K2, i.e. 1 / K1 = - 2 / K2; K1: K2 = 1: - 2

The abscissa of the intersection of line Y1 = K1X + B1 and line y2 = k2x + B2 is a, if K1

When x = a
y1=y2
Suppose that Y1 = y2 = M
k1a,y10
So Y2 and X increase
So x > a
y2>m
So Y1
