Question 17123
You have to solve for y.  This means to subtract x from each side:

x+ 4y = 4
x-x + 4y = -x + 4
4y = -x + 4


Next divide each side by 4.  It's best to divide each term by 4 in this case:
{{{(4y)/4= (-x)/4 + 4/4}}}

y = -x/4 + 1


This means that the y intercept is 1, and the slope is {{{(-1)/4}}}.  Start at the y intercept of 1, and put a point.  Then go DOWN 1 and right 4 and put the next point.  The graph should look like this:

{{{ graph (300, 300, -10, 10, -10, 10, (-x/4) + 1)}}}
