x - y = -8
3x + 7y = -14
now make the y the subject
- y = - x - 8
7y = - 3x - 14
work on both equations
make the x = 0
-y = -(0) -8
-y = - 8
-y / -1 = -8 / -1
y = 8
and make the y = 0
-y = -x - 8
-(0) = -x - 8
-y = -8
-y / -1= -8/-1
y = 8
( 8 , -8)
and other equation i given to you to do it and your graph should be negative
