 Statement is false.

For example

consider following Homogeneous system of equations

8x+12y=0

2x+3y=0

Coefficient matrix

A=`[[8,12],[2,3]]`

The solution of this system is line y=(-2/3)x

Consider following homogeneous system of equation

x+y=0

3x+4y=0

It has only trivial solution

x=y=0

This solution not represent line but a point (0,0)
