Solved by pluggable solver: Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)
Convert from standard form (Ax+By = C) to slope-intercept form (y = mx+b)


2x%2B2y=8 Start with the given equation


2x%2B2y-2x=8-2x Subtract 2x from both sides


2y=-2x%2B8 Simplify


%282y%29%2F%282%29=%28-2x%2B8%29%2F%282%29 Divide both sides by 2 to isolate y


y+=+%28-2x%29%2F%282%29%2B%288%29%2F%282%29 Break up the fraction on the right hand side


y+=+-1x%2B4 Reduce and simplify


The original equation 2x%2B2y=8 (standard form) is equivalent to y+=+-1x%2B4 (slope-intercept form)


The equation y+=+-1x%2B4 is in the form y=mx%2Bb where m=-1 is the slope and b=4 is the y intercept.
