Answer:
slope: (y₂ - y₁) / (x₂ - x₁)
(5 - 2) / (-1 - 1) = 3/-2 = -3/2
y = -3/2x + b
5 = -3/2(-1) + b
5 = 3/2 + b
b = 3.5
y = -3/2x - 7/2
(5.83 - 1.42) / (4.22 + 0.72) = 4.41/4.94
y = 4.41/4.94x + b
5.83 = (4.41/4.94)(4.22) + b
5.83 = 3.76724696 + b
b = 2.06275304
y = 4.41/4.94x + 2.06
(the numbers are really wacky so i hope thats right, so sorry if it isn't)
