What are all the subsets of the set? {–1, 9}(1 point)Responsesempty set, {–1}, {9}Image with alt text: empty set , {–1}, {9}{–1}, {9}, {–1, 9}{–1}, {9}, {–1, 9}empty set, {–1}, {9}, {–1, 9}Image with alt text: empty set , {–1}, {9}, {–1, 9}{–1}, {0}

The subsets of the set {–1, 9} are:

- The empty set: {}
- The set {-1}
- The set {9}
- The set {-1, 9}

So the correct response is: empty set, {-1}, {9}, {-1, 9}
