The commutative property, because you are simply moving the terms around without actually changing the overall value.
y - y_{1} = m(x-x_{1} )\\
y - (2) = \frac{2}{3} (x - (-1))
y - 2 = \frac{2x}{3} + \frac{2}{3}
y = \frac{2x}{3} + \frac{2}{3} + 2
y = \frac{2x}{3} + \frac{8}{3}[/tex]
y = 2x/3 + 8/3
1650 - 1200 = 450
What percent is 450 of 1200?
y = 450/1200
y = 0.375
