y=\frac{-3}{2\times 2}\left(x-\frac{1}{2}\right)+0
Express \frac{-\frac{3}{2}}{2} as a single fraction.
y=\frac{-3}{4}\left(x-\frac{1}{2}\right)+0
Multiply 2 and 2 to get 4.
y=-\frac{3}{4}\left(x-\frac{1}{2}\right)+0
Fraction \frac{-3}{4} can be rewritten as -\frac{3}{4} by extracting the negative sign.
y=-\frac{3}{4}x+\frac{3}{8}+0
Use the distributive property to multiply -\frac{3}{4} by x-\frac{1}{2}.
y=-\frac{3}{4}x+\frac{3}{8}
Add \frac{3}{8} and 0 to get \frac{3}{8}.
-\frac{3}{4}x+\frac{3}{8}=y
Swap sides so that all variable terms are on the left hand side.
-\frac{3}{4}x=y-\frac{3}{8}
Subtract \frac{3}{8} from both sides.
\frac{-\frac{3}{4}x}{-\frac{3}{4}}=\frac{y-\frac{3}{8}}{-\frac{3}{4}}
Divide both sides of the equation by -\frac{3}{4}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-\frac{3}{8}}{-\frac{3}{4}}
Dividing by -\frac{3}{4} undoes the multiplication by -\frac{3}{4}.
x=-\frac{4y}{3}+\frac{1}{2}
Divide y-\frac{3}{8} by -\frac{3}{4} by multiplying y-\frac{3}{8} by the reciprocal of -\frac{3}{4}.
