You'd have to find slope so you would use y1-y2 over x2-x1 so itd be 4-4 over 9-2 thatd equal 0/7 thats ur slope. using slope intercept form y=mx+b plug in ur slope y=0/7 x + 4 (y- intecept) then youd subtract the 0/7 x from both so youd have -0/7x+y=4 and that is in standard form.
Answer: the answer is additive identity property i just took the test
Step-by-step explanation: i hope this helps
You can round by tens
400 x 40 = 16000

A - 2b = 2 . . . (1)
a + b = 2(b + 3)
a + b = 2b + 3
a - b = 3 . . . (2)
(1) - (2) => -b = -1 => b = 1
From (2): a - 1 = 3 => a = 3 + 1 = 4
Therefore, a = 4 and b = 1
