Question

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.

Answer 1

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.
