I'm pretty sure it would be <span>x - y + 1 = 0 because if you plug in one of the coordinates into each equation, this is the only one that works.
</span><span>y - x + 1 = 0
2 - 1 + 1 = 0
2 = 0 not correct
</span><span>x - y + 1 = 0
1 - 2 + 1 = 0
0 = 0 correct
</span><span>-x - y + 1 = 0
-1 - 2 + 1 = 0
-2 = 0 not correct

6m+4 = 8m
8m-6m = 4
2m = 4
m = 2
if you are asking for 4m, then it would be 4(2) = 8
Answer:
number 8 is a rational number because it can be written as the fraction 8/1
Step-by-step explanation:
Answer:
1 : 140
Step-by-step explanation:
Ratio is 30 : 4200
Divide both numbers by 30:-
= 1 : 140 (answer)
Answer: (y-c)/m
Reasoning:
Subtract c from both sides [ y-c=mx+c-c ]
Divide m from both sides [ (y-c)/m=mx/m ]
