Question 249492
{{{2x-8y=4}}}

To find the slope and y intercept, we need to solve this equation for y.

{{{-8y=-2x+4}}}
{{{y=(-2/-8)x+(4/-8)}}}
{{{y=(1/4)x-1/2}}}

Remember now that in the equation y=mx+b, m is the slope and b is the y intercept.  So here, the slope is 1/4 and the y intercept is -1/2.
