Find out the detailed explanation of Hubei science mathematics 10 in the college entrance examination.
The coordinates of the common point are integers.

It can be known that only (8,6) (0, 10) and other 12 points match.

Moreover, it is impossible for a linear equation to be perpendicular to the X axis without passing through the origin.

A * * * has12 *11/2-4-2 = 60.

Negative 4 is perpendicular to the x axis, but does not exceed the origin.

Negative 2 crossed the origin.

Because there is a straight line with X=0, both conditions are satisfied.

So be careful not to lose weight.
