Question 316803
Use the points to find the slope.
{{{m=(y2-y1)/(x2-x1)}}}
{{{m=(5-(-1/3))/(5/6-1/6)}}}
{{{m=(15/3+1/3)/(4/6)}}}
{{{m=(16/3)/(4/6)}}}
{{{m=(16/3)*(3/2)}}}
{{{m=8}}}
Then use either point and the point-slope form of a line,
{{{y-yp=m(x-xp)}}}
{{{y-5=8(x-5/6)}}}
{{{y-5=8x-20/3)}}}
{{{y=8x-20/3+15/3}}}
{{{highlight(y=8x-5/3)}}}
