Question 118757


{{{-10x-5y+20=0}}} Start with the given equation




{{{-5y+20=0+10x}}}Add 10x to both sides



{{{-5y=0+10x-20}}}Subtract 20 from both sides



{{{-5y=10x-20}}} Combine like terms on the right side



{{{y=(10x-20)/(-5)}}} Divide both sides by -5 to isolate y




{{{y=(10x)/(-5)-(20)/(-5)}}} Break up the fraction




{{{y=-2x+4}}} Reduce



So the equation is in slope-intercept form y=mx+b where {{{m=-2}}} and {{{b=4}}}
