Write equation in standard form y-1= -1/4(x-6)
const2013 [10]

The standard form:

Ax+By=C

---------------------------------------

y-1=-\dfrac{1}{4}(x-6)         <em>use distributive property</em>

y-1=-\dfrac{1}{4}x+\dfrac{3}{2}          <em>multiply both sides by 8</em>

8y-8=-2x+4\cdot3

8y-8=-2x+12           <em>add 2x to both sides</em>

2x+8y-8=12           <em>add 8 to both sides</em>

\boxed{2x+8y=20}
