Yes, a "mudblood" (or Muggle-born) can be in Slytherin, though it is very rare. While Slytherin house traditionally favors pure-bloods, the Sorting Hat places students based on ambition, cunning, and leadership, not blood purity. There are many half-bloods (like Tom Riddle and Snape) in the house, and Scabior notes in Deathly Hallows that while uncommon, Muggle-borns can be in Slytherin. Reddit +4
In the Pottermore introduction to Slytherin, it says: nowadays you'll find plenty of people in Slytherin house who have at least one Muggle parent. So that suggests half-bloods are allowed, but not Muggle-borns.
Salazar was a pure-blood supremacist, but Slytherin house doesn't require pure blood to be sorted into it. The fact that the other founders wouldn't acquiesce to his pure- blood supremacy is what led to him leaving Hogwarts in the first place.
Slytherin was one of the four founders of Hogwarts School of Witchcraft and Wizardry along with Godric Gryffindor, Helga Hufflepuff and Rowena Ravenclaw, as well as the namesake of the Slytherin House.

Often considered the least desirable of all the sorting options, here are some reasons why Hufflepuff house is the worst. Updated November 22nd, 2020 by Ian Goodwillie: While the Hufflepuffs are endearing in their own special way, the reasons they are the worst are almost too innumerable to count.
As for Ron, Hufflepuff is probably the worst house for him. He's not hard-working (unless he really has to be), particularly tolerant (look at his treatment of Krum, for instance), or patient (see the first half of Deathly Hallows).
Ginevra "Ginny" Molly Weasley is the youngest child and only daughter of the Weasley family. She is a third year student at Hogwarts sorted into Slytherin House. She is the starting seeker on the Slytherin Quidditch team and a member of the Prince's Court.
Hermione wasn't in Ravenclaw because the Sorting Hat recognized her immense bravery, courage, and strong moral compass, qualities that aligned more with Gryffindor, and because she wanted to be in Gryffindor, valuing friendship and heroism over pure intellect, despite her brilliance. While highly intelligent, her practical, rule-following approach and willingness to break rules for the greater good fit better with Gryffindor's traits of daring and chivalry, making it a close call between the two houses.
Therefore, Harry is NOT related to Godric Gryffindor (nor, as far as we know, to Helga Hufflepuff or Rowena Ravenclaw, both of their last descendants being long deceased). He IS, however, related to Salazar Slytherin, via his pure-blood father's ancestor, Ignotus Peverell.

Page 394 in Harry Potter and the Prisoner of Azkaban discusses werewolves, a topic Snape uses to hint at Professor Lupin's secret condition during a Defense Against the Dark Arts class, but it's also the moment Harry and Hermione use a Time-Turner in the hospital wing to save Sirius Black and Buckbeak, according to some editions. The significance lies in Snape's subtle clue about Lupin's lycanthropy, which Hermione realizes, alongside the magical time travel event involving the Time-Turner, making it a pivotal moment.
