(0, 6), (2, 7)
y = mx + b
m = (7 - 6)/(2 - 0) = 1/2 = 0.5
b = 6
y = 1/2*x + 6
1/2*x - y = -6
So, answer D is correct. But m is the fraction 1/2 and not 12.
Answer:

P represents the original per pound price3p represents the cost of three pounds 3p + 3(0.75) = 5.88 multiply3p + 2.25 = 5.88 subtract 2.55 from both sides3p = 3.63 divide both sidesby 3p = 1.21 The original price was $1.21 per pound. 1.21 = 0.751.963(1.96)5.88
