Explain how you know when a linear equation in one variable has infinitely many solutions.?

A linear equation is  a line
it has infinite solutions when the equations are the same, since a line extends forever (infinity)

so exg
y=2x+4 and
2y=4x+8

they are the same line so the solutions are infinite

so when the equations are the same as each other there are infinite soltuions

I’m not sure about that
