y
) value is constant, then the translation of the straight line can be converted into (
x
) translation, translation line (
distance
) yes;
When b > 0, the straight line y=kx+b can be expressed as the straight line y=kx direction (
y
) translation (
b
) unit length;
When b < 0, the straight line y=kx+b can be expressed as the straight line y=kx direction (
It means "with ..."
) translation (
b
) unit length;
For two straight lines l1:y1= k1x+b1,L2: Y2 = K2X+B2.
When the straight line L 1 is parallel to L2, k 1 (
=
)k2，b 1(
unequal to
)B2；
When the straight line L 1 intersects L2 at the same point on the Y axis, k 1 (
unequal to
)k2，b 1(
=
)b2 .
