Answer 1

Easy way to get a medal!!!!

Answer 2

slope of -1/3 not 13

Answer 3

y = mx + b
slope(m) = -1/3
(1,2)..x = 1 and y = 2
now we sub
2 = -1/3(1) + b
2 = -1/3 + b
2 + 1/3 = b
6/3 + 1/3 = b
7/3 = b

y = -1/3x + 7/3 -- multiply entire equation by 3
3y = -x + 7 -- add x to both sides
x + 3y = 7 <== standard form
