Question

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

Answer 1

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
