2x + 5y = 10
Change to y = mx + b
subtract 2x from both sides
5y = -2x + 10
divide both sides by 5
y = -2/5x + 2
slope = -2/5
LETTER B
The answer is 5× if is wrong sorry might help you
If you meant y = 27x - 3, OK. Then, if x = 4, y = 27(4) - 3, or 108-3 = 105.
240. First You divide 420 by 7 then you multiply 60 by 4.
Hope it helped!
