Step-by-step explanation:
Answer: y=-x-8
Step-by-step explanation:
x-int: (-8, 0)
y-int: (0, -8)
m=(y2-y1)/(x2-x1)
m=(-8-0)/(0-(-8))
m=-8/(0+8)
m=-8/8
m=-1
y=mx+b
y=-x+b
-8=-0+b
b=-8
y=-x-8
Answer:
(-5, -8)
Step-by-step explanation:
-3x+3y=-9
-3x+y=7
----------------
simplify -3x+3y=-9 into x-y=3
----------------------------------------
y=x-3
-3x+y=7
------------
-3x+(x-3)=7
-3x+x-3=7
-2x-3=7
-2x=7+3
-2x=10
x=10/-2=-5
y=-5-3=-8
x=-5, y=-8
