x%2B4y=-4 Start with the given equation.


4y=-4-x Subtract x from both sides.


4y=-x-4 Rearrange the terms.


y=%28-x-4%29%2F%284%29 Divide both sides by 4 to isolate y.


y=%28%28-1%29%2F%284%29%29x%2B%28-4%29%2F%284%29 Break up the fraction.


y=-%281%2F4%29x-1 Reduce.


So the equation y=-%281%2F4%29x-1 is now in slope intercept form y=mx%2Bb where the slope is m=-1%2F4 and the y-intercept is b=-1 note: the y-intercept is the point

x+%2B+4y+=+-4...write it in slope-intercept form y=mx%2Bb, means sole for y
m=slope
b=y-intercept

4y+=+-x-4

y+=+-%281%2F4%29x-4%2F4

y+=+-%281%2F4%29x-1
so, the slope is m=-%281%2F4%29 and the y-intercept is b=-1

Add to both sides. Multiply both sides by . Your equation will then have the form

The slope will then be the coefficient on and the constant term will be the -coordinate of the -intercept.
