Question 658054
To find this, rearrange the equation so that it is in the form  y=mx+b. If you do so, b is the y intercept.

2x-4y=-12
2x-4y-2x=-12-2x
2x-2x-4y=-12-2x
0-4y=-12-2x
-4y=-12-2x
{{{-4y*(-1/4)=(-12-2x)*(-1/4)}}}
{{{y=-12*(-1/4)-2x*(-1/4)}}}
{{{y=3+x/2}}}
{{{y=x/2+3}}}
{{{y=1/2*x+3}}}

Now that you have it in the right form, m or 1/2 is the slope and 3 or b is the y-intercept.
