Question

Are these answers correct?? If not, please help

Answer 1

Explanation:

Question 4 I got something different x= 5, y= -4 (double check my work to make sure i used correct equation and all)

Also for slopes does your teacher want you to include the "x". Cuz when I think of slope its only the "m" part which means it should only be -1, -4 but its your call.
