Write the equation y=-1/2x+3 in standard form.

x + 2y - 3 = 0.

x/2 + y/9 = 1/3.

4x-y+7=0.

x + y/2 = - 1/2.

3x-y-1=0.

x - y/3 = 1/3.

Begin by multiplying both sides by 2 to get rid of the fraction. The standard form for a line is Ax + By = C, no fractions allowed. By multiplying we get 2y=-1x+3. Now move the - 1x over by adding and we have the standard form we are looking for: x + 2y = 3.
