type them both in to desmos if that is what you want to do, then copy on to your graph

not at all lol
misty1212
  • misty1212
when i sent the desmos link it did not include the graphs, you have to type them in
misty1212
  • misty1212
but they will definitely intersect at \((3,-4)\)
shelby1290
  • shelby1290
okay that's fine i'll just make do and fill in the points myself
misty1212
  • misty1212
