Answer 4

@wio double check plz

Answer 5

Do you know the slope of each line?

Answer 6

yes but I forgot what they were exactly

Answer 7

If slopes are different, then there is exactly one solution

Answer 8

If slopes are the same, then you much check the intercept

Answer 9

If the intercept is the same, there are infinite solutions (parallel lines, overlapping)
If the intercept is different, there are no solutions (parallel lines, never crossing)

Answer 10

I remember 2 and 3 were different

Answer 11

slopes.

Answer 12

and the slope for the first one is the same

Answer 13

Okay, then they look ok

Answer 14

ok thank you
