Which type(s) of equation can have infinite solutions? \( \square \) linear-linear linear-quadratic quadratic-quadratic DONE

When it comes to infinite solutions, linear-linear equations are prime contenders! These are typically represented as two lines that overlap completely, meaning every point on one line is also on the other. Imagine two identical highways running parallel forever; they are, essentially, the same path! On the other hand, quadratic-quadratic equations can also produce infinite solutions under specific conditions, such as when both parabolas are the same or completely overlap in certain sections. It’s like two magical roller coasters that perfectly align throughout their entire ride! Such scenarios create a fun mathematical adventure with solutions galore!
