answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

if you was gonna solve for a, a is a   < -12

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
