Answer:
(0,0) or Infinitely many solutions.
Step-by-step explanation:
-−4x−4y=0
−4x−4y+4y=0+4y(Add 4y to both sides)
−4x=4y
−4x/-4= 4y/-4
(Divide both sides by -4)
x=−y
4x+4y=0
4(−y)+4y=0
0=0

Answer:
equation of the table is y=30x+60
60 degrees is what the temperature starts at
to get to 440 degrees he needs 12 minutes and 40 seconds
Step-by-step explanation:
the change in y over change in x is 90/3 which is the slope
slope is 30
if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept
440=30x+60
380=30x
x=12 2/3
x= 12 minutes and 40 seconds
